1.2436 (X210CrW12) Tool Steel
1.2436 (X210CrW12)
Ledeburitic 12% chrome steel, excellent wear resistance due to the high volume of hard carbides in the steel matrix, high surface hardness after heat treatment, medium toughness, dimensionally stable, high compressive strength, not secondary hardenable. Similar to AISI D6
Manufactured by Dörrenberg Edelstahl.
Area of Application
Cutting and drawing tools for high wear resistance, rolls with high dimensional stability, deep drawing tools, tools for wire, bar and tube production, cold shear blades for thin sheets.
