1.2631/A8/SKD12/5Cr8Mo2VSI High Hardness Alloy Tool SteelProduct IntroductionSKD12 is used in a wide range of applications -Gauge,die for thread rolling,cutting tool for metal,forming roll,die for press. A8 is an air-hardening tool steel that is characterized by a combination of very good toughness, intermediate wear resistance, & excellent dimensional stability in heat treatment. A8 is an excellent steel for punches and dies that operate in the 55-60 Rockwell C hardness range. The combination of toughness and wear resistance make A8 an excellent choice for applications that require higher toughness than that of the high-carbon, high-chromium steels such as D2 & better wear resistance than that of shock-resisting steels.For hot work tooling applications, A-8 provides better resistance to erosion, wear and wash-out than the typical chromium-molybdenum hot work steels such as H11 and H13. However, it is not recommended for hot applications where thermal fatigue (heat checking) is the primary failure mode.Features
- High wear resistance
- High compressive strength
- Good dimensional stability
- Good processability
- Excellent resistance to temper softening
- Good toughness
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.
