309S Stainless steel coil tube containing sulfur, is a variant of the lower carbon 309 stainless steel, used for welding situations. It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburizing resistance. Widely used in boiler, energy, industrial furnace, incinerator, heating furnace, chemical industry, petrochemical and other important fields.

316 Stainless steel coil tube due to the addition of Mo, 316L stainless steel has excellent corrosion resistance, especially pitting corrosion resistance; High temperature strength is also very good; Excellent work hardening (weak magnetism after processing); The solid solution state is non-magnetic.

321 Stainless steel coil tube exhibits high strength, resistance to oxidation peeling and subsequent stability against aqueous solution corrosion in a temperature range up to approximately 900 degrees Celsius. It also has excellent forming and welding characteristics, can be bent or roll pressed forming, no annealing after welding. It has excellent toughness even at low temperatures.

304L Stainless steel coil tube mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure, and chromium plays a major role. Chromium has high chemical stability, which can form passivation film in cold rolled plate, isolate stainless steel from the outside world, protect cold rolled plate from oxidation, and increase the corrosion resistance of cold rolled plate. After the passivation film is damaged, the corrosion resistance decreases.

304 Stainless steel coil tube is one of the most popular products.304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. 304 stainless steel is the most widely used stainless steel, heat resistant steel. Used in food production equipment, general chemical equipment, nuclear energy, etc.

301 Stainless steel coil tube Good ductility, used for molding products. It can also be quickly hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength is better than 304 stainless steel, compared with 304, Cr and Ni content is low, after cold rolling with magnetic.

202 Stainless steel coil tube has strong corrosion resistance and can resist the corrosion of most acid and alkali media; The price is moderate, more economical and practical; Good processability, welding, cutting, stamping and so on.

201 Stainless steel coil tube, has a certain acid resistance, alkali resistance, high density, polishing no bubble, no pinhole and other characteristics, is the production of all kinds of watchcase, watchband bottom cover quality material. Mainly used to do decorative pipe, industrial pipe, some shallow stretching products.
