Product Description Product Description SKT4/L6 Die Block Steel Flat Bar for Dies and Tools1.2714 / L6 Die Block Steel is a low alloy special purpose steel containing chromium, molybdenum, vanadium, and about 1.5% nickel to improve toughness. With approximately 0.70% carbon, it can reach a quenched hardness of about 64 HRC and maintain hardness above 60 HRC even in sections up to 75 mm (3 in.) thick.This grade combines high hardness, strength, and toughness, making it suitable for heavy-duty die and tooling applications.
