Stainless steel can be divided into pressure processing steel and cutting processing steel according to the processing method; According to the structural characteristics, it can be divided into five types: austenitic, austenitic ferritic, ferritic, martensitic and precipitation hardening.
Stainless steel bars have broad application prospects, and are widely used in hardware kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, building decoration, nuclear power, aerospace, military and other industries!. Equipment for seawater, chemical, dye, paper making, oxalic acid, fertilizer and other production equipment; Food industry, coastal facilities, ropes, CD rods, bolts, nuts. Stainless steel bars can be divided into hot rolling, forging and cold drawing according to the production process. The specification of hot-rolled stainless steel round steel is 5.5-250mm. Among them, 5.5-25mm small stainless steel round steel is mostly supplied in bundles of straight bars, commonly 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 blanks.
