Cutting:
Precision cutting to standard dimensions
Custom cutting according to client specifications
Surface Grinding/Polishing:
Thickness tolerance: -0 to +0.1mm
Flatness: 0.01/100mm
Surface roughness: Ra ≤1.6 or Rz ≤6.3
Description:
special cold work tool steel, air or oil hardenable with highest toughness.
Applications:
forging tools, dies of all sorts, shapes and sizes, hot forging and pressing tools for steel and
metal. Moulds, bushings, piercers, etc.
Phisical properties (avarages values ) at ambient temperature:
Modulos of elasticity [103xN/mm2].: 210
Density [g/cm3]: 7,86
Soft annealing:
Heat to 610-850°C, cool slowly in furnace. This will produce a maximum
Brinell hardness of 295.
Stress Relieving:
Stress relieving to remove machining stresses should be carried out by heating to approx. 650°C, holding for 1-2 hours atheat, followed by air cooling.
This operation is performed to reduce distortion during heat treatment.
Hardening:
Harden from a temperature of 880-910°C followed by air or oil quenching or warm bath quenching 180-220°C. Hardness after quenching is 56 HRC.
