Chrome steel 12%, very high resistance against abrasive and adhesive wear due to a high volume of hard carbides in the steel matrix, good toughness, very good dimensional stability, high compressive strength, very good base material for PVD/CVD coating as well as nitriding due to its secondary hardening properties. Similar to SKD11 / 2379
Applications: Cutting, punching, stamping tools, shear blades, thread rolling dies, cold extrusion dies, drawing and bending tools, flanging and straightening rolls, fine cutting tools, deep drawing tools, plastic moulds for abrasive polymers.
