DIN 1.2080 also know as X210Cr12 steel ,it belongs to standard DIN EN ISO 4957. It is a widely used cold work steel with high strength, good hardenability and good wear resistance. It mainly used for cold punching dies and punches, cold cutting scissors, drill sleeves, gauges, wire drawing dies, stamping dies, thread rolling dies, drawing dies and thread rolling dies that bear small impact loads and require high wear resistance.
DIN 1.2080 Introduction
DIN 1.2080 steel is a high-carbon, high-chromium ledeburite steel . This steel has good hardenability, wear resistance, and hot workability. However , the composition don’t add VCarbides are well distributed in the steel and can be used for manufacturing Various cold work dies with complex shapes and heavy working conditions. Such as cold die punches, thread rolling dies, wire drawing dies, material dies, metallurgical powder dies, woodworking cutting tools, cold cutting scissors, drill sleeves and gauges.

Conclusion:
DIN 1.2080 mold steel is also one of the internationally used cold work mold steels, but has recently been gradually replaced by better steel types such as Cr12MoV, Cr12Mo1V1 or matrix steel. It is mainly used for cold stamping die working parts that require high wear resistance and small impact load (punch and concave dies), cold extrusion die concave dies, etc. Although its use is subject to certain restrictions due to its obvious advantages and disadvantages, it is still used in some specific areas are still irreplaceable.
