Description
OSV1 is medium Cr-Mo-V-W-Co high-speed steel with good wear resistance and toughness. The additional cobalt content produces a high degree of hot hardening and tempering resistance.
Applications
Sendzimir rolls, cutting tools, stamping, woodworking, drawing, deep drawing and pressing tools.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 217
Density [g/cm3]: 8.2

Soft Annealing
Please ask.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Please ask.
Tempering
Tempering temperature: See the data bellow.
