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

Introduction:
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.
 

 
 
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
