Will stainless steel rust? At first glance, it seems to be a false proposition.  But stainless steel rust is everywhere in life, such as the picture below!

Why does iron rust?

When iron is exposed to the air, it reacts chemically with oxygen and moisture to produce various iron oxides, which is manifested as “rust”!

What is stainless steel?

Different from normal steels , stainless steel is a type of steel that has the ability to resist atmospheric oxidation and also has the ability to resist corrosion in media containing acids, alkalis, and salts!

Introduction to stainless steel

In layman’s terms, stainless steel is steel that does not rust easily. In fact, some stainless steel has both rust resistance and acid resistance (corrosion resistance). The rustlessness and corrosion resistance of stainless steel are due to the formation of a chromium-rich oxide film (passivation film) on its surface. This film isolates the metal from the external medium, prevents the metal from being further corroded, and has the ability to repair itself. , if once damaged, the chromium in the steel will regenerate a passivation film with the oxygen in the medium to continue to play a protective role.

The decisive factor in the stainlessness of stainless steel is the chromium content. It is reported that the standards of European and American countries stipulate that the minimum chromium content cannot be less than 10.5%, Japan’s stipulation is 11%, and China’s is 12%.

Stainless steel classification

There are five basic types of stainless steel: austenitic, ferritic, martensite, duplex stainless steel, and precipitation hardening stainless steel.

There are five basic types of stainless steel: austenitic, ferritic, martensite, duplex stainless steel, and precipitation hardening stainless steel.

(1) Austenitic stainless steel is non-magnetic. The typical steel type is added with 18% chromium and contains a certain amount of nickel to increase corrosion resistance. They are widely used steel types.

(2) Ferrite is magnetic and its main content is chromium, with a proportion of 17%. This material has good oxidation resistance.

(3) Martensitic stainless steel is also magnetic. The chromium content is usually 13% and contains an appropriate proportion of carbon.

(4) Duplex stainless steel has a mixed structure of ferrite and austenite. The chromium content is between 18% and 28%, and the nickel content is between 4.5% and 8%. They have great resistance to chloride corrosion. Good results.

(5) The conventional chromium content of precipitated stainless steel is 17, with a certain amount of nickel, copper and niobium added, which can be hardened through precipitation and aging.

According to the metallographic structure, it can be divided into:

1.  Ferritic stainless steel (400 series), which is chromium stainless steel, the main representatives are 420, 440, etc.;
2. Austenitic stainless steel (300 series), chromium-nickel stainless steel, the main representatives are 304, 316, 321, etc.;
3. Martensite Stainless steel (200 series), chromium-manganese stainless steel, high carbon content, the main representatives are 1Gr13, etc.

Why stainless steel resists rust

Elements such as nickel and nickel are added to the surface of stainless steel to form an extremely thin, strong, fine, and stable chromium-rich oxide film (protective film), which prevents oxygen atoms from continuing to penetrate and oxidize, thereby gaining the ability to resist rust.

Why does stainless steel also rust?

Stainless steel will rust when the dense oxide protective layer is destroyed.

Under what conditions will the protective film be damaged?

• Bleaching powder
• Mechanical wear
• Water

Application areas of stainless steel

There are many types of stainless steel, with different properties and different use environments.

301—Good ductility, used for molded products. It can also be hardened by mechanical processing with good weldability. Furthermore，wear resistance and fatigue strength are better than 304 stainless steel.

302—The corrosion resistance is the same as that of 304, but its strength is better due to its relatively higher carbon content. Often used in the food industry

316—Compare with 304, the 316  most widely used steel type, mainly used in the food industry and surgical equipment, the addition of molybdenum gives it a special structure that resists corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as “marine steel”. SS316 is usually used in nuclear fuel recovery devices.

420—”Cutting grade” martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. Also used in surgical knives, which can be made very shiny.

430—ferritic stainless steel, for decorative purposes, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.

440—High-strength cutting tool steel with slightly higher carbon content. After appropriate heat treatment, it can obtain higher yield strength and its hardness can reach 58HRC, which is among the hardest stainless steels. The most common application example is “razor blades”. There are three commonly used models: 440A, 440B, 440C, and 440F (easy-to-process type).

In addition to 300 series and 400 series, there are also 500 series – heat-resistant chromium alloy steel, 600 series – martensitic precipitation hardening stainless steel

Stainless steel materials may rust due to the following reasons:

 There are chloride ions in the use environment

Chloride ions exist widely, such as table salt/sweat stains/sea water/sea breeze/soil, etc. Stainless steel corrodes very quickly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the environment in which stainless steel is used, and it needs to be wiped frequently to remove dust and keep it clean and dry. (This would give him an “inappropriate use” rating.)

Without solid solution treatment

The alloy elements are not dissolved into the matrix, resulting in a low alloy content in the matrix structure and poor corrosion resistance.

Natural intergranular corrosion

This titanium- and niobium-free material is prone to intergranular corrosion.

The most common ways to destroy the passive film of stainless steel in daily life are as follows:

1. Dust containing other metal elements or attachments of heterogeneous metal particles accumulate on the surface of stainless steel. In humid air, the condensed water between the attachments and stainless steel connects the two into a micro-battery, triggering an electrochemical reaction. , the protective film is damaged, which is called electrochemical corrosion.

2. Organic juice (such as vegetables, noodle soup, etc.) adheres to the surface of stainless steel. In the presence of water and oxygen, it forms organic acid. For a long time, the organic acid corrodes the metal surface.

3. The surface of stainless steel contains acid, alkali, and salt substances (such as alkaline water and lime water splash on the wall decoration), causing local corrosion.

4. In polluted air (such as an atmosphere containing a large amount of sulfides, carbon oxides, and nitrogen oxides), when encountering condensed water, sulfuric acid, nitric acid, and acetic acid liquid points will form, causing chemical corrosion.

To ensure that metal surfaces are permanently bright and free from rust, here are some suggestions:

1. The surface of decorative stainless steel must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause modification.

2. 316 stainless steel should be used in seaside areas. 316 material can resist seawater corrosion.

3. The chemical composition of some stainless steel pipes on the market cannot meet the corresponding national standards and cannot meet the 304 material requirements. Therefore, it will also cause rust, which requires users to carefully choose products from reputable manufacturers.

So stainless steel is not that it will not rust, but it is not easy to rust!

Cr in steel is one of the main composition  composing steel, and its content directly affects the corrosion resistance and hardenability of steel. What are the main effects of Cr in steel? Last artical we talked about the relationship between Nickel(Ni) and steel. This article details the properties, microstructure, and application of Cr on steel.

Chromium（Cr） on the microstructure and heat treatment of steel

• Chromium and iron can form a continuous solid solution and reduce the austenite phase area. Chromium forms various carbides with carbon, and its affinity with carbon is greater than iron and manganese but lower than tungsten, molybdenum, etc.
• Chromium can reduce the concentration of carbon in pearlite and the ultimate solubility of carbon in austenite.
• Slow down the decomposition rate of austenite and significantly improve the hardenability of steel, but also increase the temper brittleness tendency of steel.

The influence of chromium(Cr) on the mechanical properties of steel

• Improve the strength and hardness of steel. Chromium can improve the strength and hardness of carbon steel in its rolling state, and reduce the elongation and area shrinkage. When the chromium content more than  15%, the strength and hardness will decrease, and the elongation and area reduction will increase accordingly. Parts containing chromium steel can easily obtain higher surface processing quality after grinding.
• Chromium can increase the hardenability of steel and have a secondary hardening effect, which can improve the hardness and wear resistance of carbon steel without making the steel brittle. When the content more than 12%, the steel has good high-temperature oxidation resistance and oxidation corrosion resistance, and also increases the thermal strength of the steel, such as Cr12MoV. Chromium is the main alloying element of stainless steel, acid-resistant steel and heat-resistant steel.
• Significantly increase the ductile-brittle transition temperature of steel.
• The impact toughness drops sharply when the chromium content is high.

The influence of chromium(Cr) on the physical, chemical and process properties of steel

• Improve the wear resistance of steel and easily obtain lower surface roughness values. The electroplating industry widely uses chromium plating technology to improve the wear resistance and aesthetics of products, as shown in the figure below.
• Reduce the conductivity and temperature coefficient of resistance of steel.
• Improve the coercive force and residual magnetic induction of steel, and are widely used in the manufacture of permanent magnet steel tools.
• Chromium forms a passivation film on the surface of steel, which significantly improves the corrosion resistance of steel; but when carbides containing chromium precipitate, the corrosion resistance of steel decreases.
•  Improve the oxidation resistance of steel.
• Dendritic segregation is easy to form in chromium steel, which reduces the plasticity of the steel.
• Since chromium reduces the thermal conductivity of steel, one must slowly heat it during hot processing and slowly cool it after forging and rolling.

Application of Chromium(Cr) in Steel

• Chromium is mainly used in alloy structural steel to improve hardenability, and chromium-containing carbides can be formed on the carburized surface to improve its wear resistance.
•  Chromium and other elements are used in spring steel to improve the overall performance of the steel.
• The use of chromium in bearing steel improves wear resistance and has the advantages of small surface roughness after grinding.
• In tool steel and high-speed steel, it mainly use chromium to improve wear resistance, and it has certain advantages such as tempering resistance and toughness.
• Chromium often applicate in combination with manganese, nitrogen, and nickel in stainless steel and heat-resistant steel. When austenitic steel needs to form, there must be a certain ratio between chromium that stabilizes ferrite and manganese and nickel that stabilize austenite. Such as Cr18Ni9, etc.

We all know that in addition to iron and carbon, the main elements of steel include silicon, manganese, sulfur, phosphorus, etc. And Nickel(Ni) and steel have a good relationship when it express some specail properties .Nickel is one of the main elements that improves and enhances the properties of steel. So what is the main role of nickel in steel? This article details the relationship between Nickel(Ni) and steel.

How does Ni affects the microstructure and heat treatment of steel ?

1. Nickel and iron can form infinite solid solutions. Nickel expands the austenite zone of iron and is the main alloy element that forms and stabilizes austenite.
2. Nickel and carbon do not form carbides.
3. Reduce the critical transformation temperature, reduce the diffusion rate of various elements in steel, and improve hardenability.
4. Reduce the carbon content of eutectoid pearlite, its effect is second only to nitrogen but stronger than manganese. It is about half as effective as manganese in reducing the martensitic transformation temperature.

The influence of nickel on the mechanical properties of steel

1. Strengthen ferrite and refine and increase pearlite to improve the strength of steel and have little impact on the plasticity of steel.
2. The carbon content of nickel-containing steel can be appropriately reduced, thus improving the toughness and plasticity.
3. Improve the fatigue properties of steel and reduce the sensitivity of steel to notches.
4.  Since it is not very effective in improving the hardenability and tempering stability of steel, nickel is of little significance to quenched and tempered steel.

The influence of nickel on the physical, chemical and process properties of steel

1.  Greatly reduce the thermal conductivity and electrical conductivity of steel.
2. Steel with a mass fraction of nickel less than 30% is paramagnetic (i.e. non-magnetic steel), and iron-nickel alloys with a mass fraction of nickel greater than 30% are important precision soft magnetic materials.
3.  Steel with a nickel mass fraction of 15%-20% or higher has high corrosion resistance to sulfuric acid and hydrochloric acid, but is not resistant to nitric acid corrosion. In summary, nickel-containing steel has certain corrosion resistance to acids, alkalis and the atmosphere.
4. Austenitic electrodes should be used when welding steel with high nickel content to prevent the occurrence of cracks.
5. Banded structure and white spot defects are prone to occur in nickel-containing steel, which should be prevented in the production process.

Application of Nickel in steel

1. Pure nickel steel is only used when there are particularly high impact toughness or very low working temperature requirements.
2.  Nickel-chromium or nickel-chromium-molybdenum steel used in machinery manufacturing can obtain comprehensive mechanical properties with good strength and toughness after heat treatment. Nickel-containing steel is particularly suitable for parts that require surface carburization, as shown in the figure. a) Cam mechanism shaft b) Drive shaft
3. Nickel is an austenitizing element in high-alloy austenitic stainless heat-resistant steel, which can provide good comprehensive properties. It is mainly Ni-Cr series steel ，also know as stainless steel, such as 304 stainless steel
4. Since nickel is relatively scarce and an important strategic material, it is relatively expensive. Therefore, it will be used unless it is impossible to meet the performance requirements with other alloy elements. If you are pursuing cost-effectiveness, you can choose the steel with nickel-free or with a less nickel content to instead.

In conclusion

1. Nickel strengthens steel, increasing strength without compromising plasticity.
2. Nickel boosts strength in low carbon steel without sacrificing toughness.
3. Nickel enhances steel strength with minimal impact on toughness and plasticity.
4. Nickel in medium carbon steel reduces pearlite, increasing strength or allowing carbon reduction to enhance toughness.
5. Nickel improves steel fatigue resistance and reduces notch sensitivity.
6. Nickel lowers low-temperature brittleness, enhancing steel toughness for cold applications.
7. High nickel content alters iron-nickel alloy expansion coefficients, useful for specialized materials.
8. Nickel in steel provides corrosion resistance to acids, alkalis, atmosphere, and salt, vital for stainless steel.
