1.2379 (X153CrMoV12 ) Tool Steel
1.2379 (X153CrMoV12 )
Ledeburitic 12% chrome steel, 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 AISI D2.
Manufactured by Dörrenberg Edelstahl.
Area of Application
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.
