A new type of high strength and toughness special wear-resistant cold stamping die steel developed by LD domestically, which not only has high hardness but also good toughness; Adding Cr, Mo, and V elements is beneficial for secondary hardening, ensuring that the steel has high hardness, strength, and good wear resistance; Add a certain amount of Si to strengthen the matrix and improve tempering stability.
LD composition（％）：
C 0.70～0.80 Si 0.70～1.20 Cr 6.50～7.00 Mo2.00～2.50
V1.70～2.20 Mn≤0.40 P≤0.030 S ≤0.030
Purpose:
1.Suitable for manufacturing various large and medium-sized punching molds with complex shapes, high resistance to impact and bending stress, and high wear resistance requirements. Re cut cold heading and extrusion molds, as well as various large and medium-sized punching molds with high grinding performance. Re cutting cold heading and cold extrusion molds, also.
2.LD steel has been widely used in the manufacturing of various cold working molds with high impact and bending stresses, as well as requirements for wear resistance, such as cold forging, cold stamping, cold pressing, and cold bending.
3.Can be used for bolt cold heading and smooth stamping dies, bolt cold heading and edge cutting dies, and nut cold heading and pressing ball dies.
