3.the performance advantages and the uses

 

Severely stressed machine blades for cellulose and paper ind., woodworking milling cutters, flat and circular blades for cutting 5 to 15 mm thick sheet/plate.  

4.Soft AnnealingHeat to 820-860oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.5.Stress RelievingStress relieving to remove machining stresses should be carried out by heating to 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.6.HardeningHarden from a temperature of 1000-1040oC followed by oil or air quenching. Hardness after quenching is 57 HRC.
