Heat treatment and differentiation of circular saws
After heat treatment and heat treatment quality of blade is good not chipping, no bending, no crack, high hardness, good abrasion resistance, long service life, without heat treatment used not to live, don't have those advantages.
The heat treatment of circular saw is the heat treatment of saw blade. Generally, spheroidizing annealing is adopted to reduce hardness, facilitate machining, adjust the microstructure and prepare for final heat treatment. The final heat treatment usually adopts quenching + low temperature tempering. Maintain high hardness and wear resistance.
