Specifications
D3 steel also knows as DIN 1.2080 and JIS SKD1, which is a 12% chrome alloy steel. JIS SKD1 steel has very high wear resistance against abrasive and adhesive wear due to the high volume of hard carbides in the steel matrix, medium toughness, dimensionally stable, high compressive strength, not secondary hardenable.
Applications:
1.High stressed cutting and punching tools
2.Drawing and deep drawing tools
3.Stone processing tools
4.Thread rolling dies
