SAE1055 annealed steel strip for shoes shank
We mainly produce bright annealing steel strips and spherodized steel strips.Bright annealing is to put steel coil intoconfined space of annealing furnace and heat it to a high temperature.At this point, a suitable temperature is maintained. After this, thesteel inside annealing furnace, is cooled slowly and then comes to bright surface, which won`t cause decarbonization.
Spheroidization is achieved by holding steel for a prolonged period at temperatures near the lower critical point or by a cyclic heating and
subsequent cooling close to these temperatures. The process can be accelerated by prior deformation or hardening. Spheriodized steel strips are used for various application requiring maximum cold forming.
