75Cr1/1.2003

Chemical Composition

carbon (C) 0.70-0.80%

chromium (Cr) 0.90-1.20%

silicon (Si) ≤ 0.50%

manganese (Mn) ≤ 0.80%

phosphorus (P) ≤ 0.03%

sulfur (S) ≤ 0.03%

The combination of high carbon and moderate chromium endows it with high hardness and hardenability.

Physical Performance

Mechanical properties:

Tensile strength ≥ 1600MPa, hardness up to 47-51 HRC, excellent wear resistance, high elastic limit, fatigue strength, and tempering stability.

Other characteristics:

Good thermal stability, corrosion resistance, small deformation after heat treatment, suitable for precision machining.

Main Purpose

Tool manufacturing: used for small tools such as punches, core rods, razors, and tamping tools.

Mold applications: cold heading die, cold extrusion die, punching die (cutting die, trimming die), bending die and drawing die.

Saw blade material: suitable for cutting tools such as band saws and circular saws that require high hardness and wear resistance.
