Type properties


According to the production process, stainless steel round steel can be divided into hot rolling, forging and cold drawing. The specification of hot rolled stainless steel round steel is 5.5-250mm. Among them, small stainless steel round steel of 5.5-25mm is mostly supplied in bundles of straight bars, which is often used as reinforcement, bolts and various mechanical parts; Stainless steel round steel larger than 25mm is mainly used for manufacturing mechanical parts or seamless steel tube billets.

Surface treatment: industrial surface, wire drawing surface, bright surface, RE polishing;


Cost calculation: round steel price * [1 - (10 discount) / 10] + rolling cost + polishing cost + sizing cost + packaging + transportation.
