1) The appearance of cold-rolled products has good gloss and beautiful appearance; 2) Due to the addition of Mo, it has excellent corrosion resistance, especially pitting corrosion resistance; 3) Excellent high temperature strength; 4) Excellent work hardening (weak magnetic after processing); 5) Non-magnetic in solid solution state. Used in hardware and kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electric power, energy, aerospace, etc., building decoration. Equipment used in sea water, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.Stainless steel round steel belongs to the category of long products and bars. The so-called stainless steel round steel refers to long products with uniform circular cross-section, generally about four meters in length. It can be divided into light circles and black rods. The so-called smooth circle refers to the smooth surface, which is obtained by quasi-rolling treatment; and the so-called black bar refers to the black and rough surface, which is directly hot rolled. According to the production process, stainless steel round steel can be divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled stainless steel round bars are 5.5-250 mm. Among them: small stainless steel round bars of 5.5-25 mm are mostly supplied in bundles of straight bars, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used for the manufacture of mechanical parts or seamless steel pipe billets.
