Product Description

1. Composition:

   • Carbon : 2.00% - 2.35%
   • Chromium (Cr): 11.00% - 13.50%
   • Silicon (Si): 0.60%
   • Manganese (Mn): 0.60%
   • Nickel (Ni): 0.30%
   • Vanadium (V): 1.00%
   • Copper (Cu): 0.02%
   • Tungsten (W): 1.00%

2. Properties:

   • Hardness: HCHCR D3 steel achieves a hardness in the range of 58-64 HRC after proper heat treatment.
   • Wear Resistance: Excellent abrasion/wear resistance.
   • Applications: Ideal for highly stressed cutting tools, punching tools for thin sheets, shear blades for cutting, profile rolls, drawing and deep drawing tools, stone processing tools, knives for paper and plastics, and shear knives for thin sheets.

3. Heat Treatment:

   • Hardening: It is preferable to heat the tools in a controlled atmosphere. If this is not possible, pack hardening is recommended. Preheat the component to 750-800C and allow it to soak at this temperature. Raise to the hardening temperature of 950-980C. Soak thoroughly at the temperature for thirty minutes per 25mm of ruling section, then cool or quench accordingly.
   • Tempering: Double tempering is recommended. Tempering should be done with the least possible delay after hardening, preferably when the tools are still hand warm. Select a suitable tempering temperature, bearing in mind the service requirements.
