Product Description

A2 A8 1.2631 SKD12 Special Alloy Steel Cold Work Tool & Die Steel 
 
1. Standard: JIS G4404:2000

2. Similar grade: A2, BA2, 2231Z100CDV5

3. Heat treatment hardness: 58-61HRC

4. Features:
1. This is alloy mould steel with medium Alloy content ,due to contain molybdenum and vanadium, so that it has good hardenability,
2. SKD12 Steel has good impact toughness and good wear resistance cause to uniform distribution of carbide,
3. Good Air quenching performance,
4. Small quenching deformation ,
5. Toughness is better than 9Mn2V,Cr12
6. Uniform and fine carbide, good wear resistance.

5. Advance:
1, air quenching mould steel has excellent air quenching hardening
2, good wear resistance performance,
3, Micro deformation,
4, High hardenability,
5, High compressive strength

6. Heat treatment:
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
