D2 steel is a cold working die steel with high wear resistance and micro deformation, which belongs to wind hardening tool steel. The carbon content of the steel is as high as 1.5% and the chromium content is as high as 11.5%. After heat treatment, the hardness can reach 60HRC, but the ductility, toughness and rust resistance of the steel are relatively weak, and the steel surface is difficult to be polished by mirror.

With the development of cold stamping products towards high precision, high efficiency and variety, die steel is required to have better wear resistance and toughness. The results show that the wear resistance of the steel is better than that of the cast steel. As the yield point and plastic deformation resistance of the steel are higher than that of SKD11 steel, its forging property and thermoplastic formability are slightly worse than that of SKD11 steel.

chemical composition

element C Si Mn Cr V Mo
Percentage (%) 1.40-1.60 0.30-0.50
0.30-0.50 11.0-13.0 zero point eight zero 0.70-1.20

advantage

1. Good processability, stable heat treatment size

2. Excellent machining type

3. Excellent dimensional stability when hardened

4. After quenching and tempering, the high surface hardness and the body toughness are well matched

characteristic

High wear resistance, vacuum heat treatment to HRC60 ° to 62 ° and excellent processing performance.

purpose

Used for metal stamping die, drawing die, stainless steel sheet blanking die, high hardness blanking die, shearing knife die, rubbing wire die, hardware parts manufacturing, machinery manufacturing, etc.

Application examples

1. Used for drawing die of refrigerator compressor back cover, quenching hardness 56 ~ 58 HRC.

2. In order to improve the service life of D2 cold work die flat steel, the wear resistance and impact toughness of the steel are greatly improved by adding rare earth, so as to improve the service life of flat steel for round die.

3. Because the content of V and Mo in D2 steel is higher than that of Cr12MoV steel, D2 steel has better comprehensive properties, and the traditional Cr12MoV steel will be gradually replaced.

4. Compared with Cr12MoV steel, the service life of cold stamping die made of D2 steel for thread rolling wheel and off stage adjusting plate can be increased by 5 ~ 6 times.
