Product Description

SKD12 Cold Work Alloy Die Steel Round Bar

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:
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.

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.

Application
Widely suitable for Large and complex for a variety of hardware Die, and bear a greater impact load punch die.
1, 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.
2, 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.
3, The steel can be used for thread rolling die can be used for processing aluminum and copper alloys.
4, Stretch film, embossing dies, die cutting, stamping die.
