Product Description

SKD12 high grade cold work mould steel


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 u niform 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

Heat treatment
Annealing:1,800-850 ºC , slow cooling  2,Spheroidizing
Quenching:940-960 ºC , air cooling
Tempering:180-220 ºC , air cooling HRC=60-64 510-520 ºC , air cooing HRC=57-60

Supply states : Spheroidizing HB ≤ 230

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.
