Cr12MoV is a high-carbon, high-chromium ledeburite steel. It exhibits high hardenability and wear resistance, with minimal dimensional change during quenching. It is a widely used cold-working die steel. Compared to Cr12 steel, it has a more evenly distributed carbide content and higher toughness. It can be used to manufacture complex-shaped punching dies, cold shears, drawing dies, wire drawing dies, thread rolling plates, cold extrusion dies, and measuring tools.
SKD11 mold is a high carbon high chromium alloy tool steel, belonging to the cold working die steel, with high wear resistance. After heat treatment, it has high hardness and wear resistance, and has good hardenability and dimensional stability.
Cr12 is an alloy tool steel with good hardenability and good wear resistance. It is mainly used for cold stamping dies and punches, cold cutting shears, drill sleeves, gauges, wire drawing dies, stamping dies, thread rolling plates, drawing dies and thread rolling dies that require low impact loads and high wear resistance.
DC53 steel boasts twice the toughness of SKD11, making it suitable for complex punching and drawing dies, with significantly improved resistance to cracking and chipping. Even after high-temperature tempering at 520-530°C, it still achieves a hardness of 61-63 HRC, reducing the risk of cracking accidents caused by residual stress in wire-cut machining dies. Suitable for surface hardening, it significantly extends the life of the mold. With high hardenability and wear resistance, and minimal dimensional change during quenching, it is a widely used cold-work die steel.
