DIN 1.2379 steel is Ledeburitic 12% chrome steel, very high resistanceagainst abrasive and adhesive wear due to a highvolume of hard carbides in the steel matrix, goodtoughness,very gooddimensional stability, highcompressive strength, very good base material forPVD/CVD coating as well as nitriding due to itssecondary hardening properties.
