Product Description

431 321 Stainless Steel Round Bar Hardness 270

Product Description

         The stainless steel rod produced by our company is a versatile metal material that has high strength, corrosion resistance, and high temperature resistance. Therefore, it is widely used in industries such as construction, catering, medical, and aviation.It also has many shapes, including stainless steel bars made of round steel, square steel, flat steel, hexagonal steel, and octagonal steel.Stainless steel bars can be divided into three types according to production processes: hot rolling, forging, and cold drawing. The specification of hot-rolled stainless steel round steel is 5.5-250 millimeters. Among them: 5.5-25mm small stainless steel round steel is mostly supplied in bundles of straight bars, commonly used as steel bars, bolts, and various mechanical parts; Stainless steel round bars larger than 25 millimeters are mainly used for manufacturing mechanical parts or as seamless steel pipe billets.
