Hardness for the annealing-process is listed normally on HRB scale, at the maximum value. this process is performed for refining grain size, improving strength, affecting electromagnetic properties and removing residual stress.  

Steels are especially suitable for heat treatment since they react well to heat treatment and the business utilization of steels surpasses that of some other material. Steels are heat treated for one of the accompanying reasons:   Softening: Softening is carried out to diminish quality or hardness, evacuate leftover burdens, enhance toughness, restore malleability, refine […]
