KL (1.2550) Steel

Steel name: KL (1.2550)
Diagram No.: 2510
Mat.No. (Wr.Nr.) designation: 1.2550
DIN designation: 60WCrV8
Chemical composition in weight %: 0.60% C, 0.75% Si, 0.30% Mn, 1.10% Cr, 0.15% C, 2.00% W
Steel group: Cold work tool steels
Properties: KL is an oil-hardenable steel with very good toughness and relatively good cutting performance. The hardenability capacity is moderate for large cross-sections.
Applications: Cutting and punching tools for sheet metal thicknesses of approx. 6-12 mm. Cold punches. Deburring tools. Profile shear blades. Woodworking tools. Small stamping tools. Ejectors and similar tools. Cutting tools for soft, medium-temperature cutting material (gently preheat tools).
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 870 - 900 °C. Interrupt oil cooling at approx. 150 °C.
Tempering: For hot work 550 - 600 °C.
