Product Description
SKD12 high grade cold work mould steel
Standard: JIS G4404:2000
Similar grade: A2, BA2, 2231Z100CDV5
Heat treatment hardness: 58-61HRC

SKD12 case of air quenching tool steel with deep air-hardening properties, which requires tempering after quenching quenching and tempering must maintain its 
complex shape of the mold is extremely useful. 

The air quenching of steel due to the deformation caused by manganese-based oil is only about 1/4 of quenching tool steel, the wear resistance between manganese oxide and high carbon high chromium tool steel, toughness better than any one particular It requires suitable for good wear resistance but also has good toughness, special tools, widely used in die cutting and forming dies, roll, punch, rolling dies and thread rolling dies, but also for certain types of scissors sheet.


This is alloy mould steel with medium Alloy content ,due to contain molybdenum and vanadium, so that it has good hardenability, 

SKD12 Steel has good impact toughness and good wear resistance cause to uniform distribution of carbide, 

Good Air quenching performance

Small quenching deformation

Toughness is better than 9Mn2V,Cr12

Uniform and fine carbide, good wear resistance


Air quenching mould steel has excellent air quenching hardening

Good wear resistance performance

Micro deformation

High hardenability

High compressive strength 

Annealing:1,800-850oC, slow cooling  2,Spheroidizing

Quenching:940-960oC, air cooling

Tempering:180-220oC, air cooling  HRc=60-64 510-520oC, air cooing  HRc=57-60
Spheroidizing HB≤230


Widely suitable for Large and complex for a variety of hardware Die, and bear a greater impact load punch die.
For bending carbon content of 0.65% to 0.80% of the leaf spring that the hardness 37~42HRC, service life up to 11~12w times.

For bending carbon content of 0.65%~0.80%spring steel plate that the hardness 37~42HRC, And then add nitriding treatment, life expectancy of up to 40 million times. 

The steel can be used for thread rolling die can be used for processing aluminum and copper alloys

Stretch film, embossing dies, die cutting, stamping die.
