Cold Work Tool Steel

1.2379 steel is mainly used for high wear-resistant cold work molds (such as stamping molds, shearing knives), precision plastic molds (especially fiberglass reinforced injection molds), and rolling tools, and is suitable for large-scale production scenarios in industries such as automotive and electronics.

D2 steel is suitable for making all kinds of cold stamping dies with large cross-section and complex shape, as well as cold cutting scissors and thread taking plates; Cold extrusion forming, trimming die, etc

As a benchmark for high carbon and high chromium cold work die steel, D2 steel's core highlight lies in the precise ratio of 12% chromium content and 1.5% carbon to form a large number of hard carbides. It maintains an ultra-high hardness of 60-62HRC while also having better wear resistance than ordinary tool steel (5-8 times that of ordinary steel). After appropriate heat treatment, D2 steel can significantly improve its anti cracking performance, especially suitable for high-strength wear scenarios such as precision punching dies and shear cutting tools. D2 steel, known as "semi stainless steel", also forms a passive film on its surface to delay corrosion, becoming a classic choice for balancing performance and cost in the industrial field.

1.2080 steel has high wear resistance and long service life, and is suitable for various cold stamping dies, cold shear blades, thread take-up plates and other complex and possibly deformed tool dies.

O1 mold steel is widely used. O1 steel has good processability, good wear resistance, stable O1 heat treatment performance, small dimensional deformation, but weak toughness and corrosion resistance. It is commonly used in blanking die, punching die, punching die, punching die, etc.

As a representative of high-end cold work die steel, D6 steel's core highlight lies in achieving excellent balance between wear resistance and crack resistance through high carbon and high chromium alloy design, and significantly improving dimensional stability through deep cryogenic treatment technology; D6 steel exhibits excellent deformation resistance and durability in harsh working conditions such as silicon steel sheet punching and precision processing of high-strength steel plates, while also possessing good corrosion resistance, making it an ideal choice for high-precision and high load mold manufacturing.

D3 steel is suitable for concave and convex dies, inserts, stretching and blanking dies, wire rollers, punches, scissors, etc. with complex shapes.

X210Cr12 steel has high wear resistance and long service life, and is suitable for various cold stamping dies, cold shear blades, thread take-up plates and other complex and possibly deformed tool dies.

Cr12 Steel is suitable for the manufacture of cold working dies with complex shape and requiring wear resistance, small deformation and stress, such as silicon steel sheet punching die, thread rolling die and drawing die.

K110 steel is a high carbon, high chromium cold work die steel with extremely high hardness, excellent wear resistance, and good toughness, making it a typical wind hardening tool steel. K110 steel has good dimensional stability during heat treatment and is suitable for high-precision, high load cold work mold manufacturing.
