Characteristic and application: Cr12 steel is a kind of cold work die steel widely used. The steel has good hardenability and wears resistance. Because the carbon content of Cr12 steel is as high as 2.3%, the impact toughness is poor, easy to crack, and easy to form heterogeneous eutectic carbide. Cr12 steel due to its good wear resistance, is More for the manufacture of small impact load requirements of high wear-resistant cold die, punch, blanking die, cold upsetting, cold extruding die of the punch and flat die, drill sleeve, gauge, wire drawing die, stamping die, thread rolling plate, drawing die and powder metallurgy with cold die.

10, DCCr12MoV - wear-resistant chromium steel
Compared with Cr12 steel, the carbon content is lower, and with the addition of Mo and V, the carbide heterogeneity is improved. MO can reduce carbide segregation and improve hardenability, and V can refine grain size and increase toughness. This steel has high hardenability, section below 400mm can be completely quenched. 300 ~ 400 °C can still maintain good hardness and wear resistance, compared with Cr12 has high toughness, the quenching volume change is small, but also has high wear resistance and good comprehensive mechanical properties.
