Applications
Manufacture the piston, valve, valve seat of fuel pump of diesel engine. Cutting tools, Mechanical parts, Air hammer tools and Piercing tools.


Heat Treatment
Annealing
710 to 750 °C
hardness max. 255 HB


Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650 °C, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Quenching
830 to 860 °C
Cooling medium: water/oil


Tempering
240 to 350 °C
After tempering hardness is 50 to 61 HRC.
