Application scope of cold working die steel

Cold working die steel focuses on hardness, wear resistance and high carbon content. Alloy elements mainly increase hardenability and wear resistance. Cold working die steel has the characteristics of manufacturing dies for punching and cutting (blanking and punching dies, trimming dies, punches, scissors), cold heading dies, extrusion dies, bending dies, drawing dies, etc.

1.2379 steel: It is a high carbon, high chromium tool steel that has high hardness and wear resistance after heat treatment, and has strong hardenability and good dimensional stability. It is a semi stainless steel with a carbon content of 5% and a chromium content of 15%. After heat treatment, the hardness can reach 60HRC. In addition, it has good wear resistance and corrosion resistance.

D2 steel: This is a high carbon and high chromium tool steel that meets the ASTM A 681 standard for molybdenum and vanadium alloying, and is the most commonly used steel in Group D. It has good hardenability, high quenching stability, and good tempering resistance. Usually provided in an annealed state, suitable for applications that require long runs and precise tolerances.

SKD11 steel: It is a high carbon, high chromium, molybdenum, vanadium, air hardened tool steel with high surface hardness, good wear resistance, through-hole hardenability, dimensional stability, and high tempering resistance. It is also suitable for vacuum quenching.

D6 steel: It is a common cold work mold steel with certain wear resistance and toughness. It is usually used to manufacture various molds, such as plastic molds, die-casting molds, etc.

These steels have good hardness and wear resistance, making them suitable for making various cold work molds. The choice of material depends on specific application requirements and performance requirements.
