Stainless steel rod is a cylindrical stainless steel product, which is widely used in auto parts, aviation, aerospace hardware tools, chemical industry and other industries. The main raw materials used for stainless steel rods are 200 series, 300 series and 400 series. Among them, the common 304 stainless steel rod has good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics, good thermal processing properties such as stamping and bending, and no heat treatment hardening. It is mainly used in the tableware, cabinets, boilers, auto parts, medical devices, building materials and food industries.
