Cold Work 1.2379 / D2 / SKD11 Plastic Mold Steel Plate For Making Cutting Tools

 

 

Introduction

 

D2 steel is a high wear resistant micro deformation cold working die steel, belonging to air hardening tool steel. With high quality fraction of carbon and high chronic, the hardness can up to 60HRC after heat treatment, but malleability,toughness,rust resistance is not good and the surface of the steel is also difficult to be polished.

 

 

Chemical Composition(%):

 

C Si Mn Cr Mo V P S
1.40-1.60 0.30-0.50 0.30-0.50 11.0-13.0 0.70-1.20 ≤0.8 ≤0.030 ≤0.030

 

 

Available size(mm):

 

Flat Bar Size(mm) Round bar Size(mm)
Thickness Width Length Diameter Length
8-80 155-610 3000-6000 14-80 300-6000

 

 

Feature:

 

1,Good processing, heat treatment size stability.
2,Excellent machinability.
3,Excellent dimensional stability when hardened.
4,After hardening and tempering, the high surface hardness match well with the toughness of the body.

 

 

Applications:

 

For metal stamping die, drawing die, stainless steel sheet punching die, high hardness punching die, cutting knife mold, Roll Die, metal parts production, machinery manufacturing etc.
(1) Used for drawing die of refrigerator compressor rear cover, quenching hardness 56~58HRC.
(2) In order to improve the service life of flat rolling material for D2 cold working die, the wear resistance and impact toughness of steel are greatly improved by adding rare earth, so as to improve the service life of flat rolling material of round die.
(3) Because the content of V and Mo in D2 steel is higher than that of Cr12MoV steel, it has better comprehensive properties, and the traditional Cr12MoV steel will be replaced gradually.
(4) Made of D2 steel rolling wheels, from Taiwan palette die, and Cr12MoV can improve the service life of steel compared to 5 ~6 times.

 

 

Recommend heat treatment:

 

Quenching Tempering
Heating temperature/℃ Cooling Hardness/HRC Heating temperature/℃ Cooling Hardness/HRC
980-1040 Oil or Air 60-65 180-220 Air 60-64
1060-1100 60-65 510-540 Air 60-64

 

 

With the development of cold stamping products moving towards high accuracy,high efficiency,varieties, we require the mould steel should has good wear resistance and high toughness.

 

Compared with Cr12MoV steel, this D2 die steel adds Mo,V compositions,changed the steel cast structure, improved the morphology of ledeburite , toughness and wear resistance are better than Cr12MoV steel, improved the service life as well.Because of the yield point and plastic deformation resistance is higher than Cr12MoV steel, so that forging performance and hot molding properties are a little weak than Cr12MoV steel.
