Features |
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 |
|
Advance |
Air quenching mould steel has excellent air quenching hardening |
Good wear resistance performance |
|
Micro deformation |
|
High hardenability |
|
High compressive strength |
|
