304H Stainless steel color tube has good oxidation resistance and thermal stability in high temperature environment, can maintain a long service life in high temperature oxidation environment. With good resistance to chemical penetration, it has a good application prospect in sealing parts, storage tanks and other occasions that need to prevent chemical penetration.

347H Stainless steel color tube austenitic stainless hot strong steel, with good corrosion resistance, welding performance and thermal strength. 347H stainless steel is used for large boiler superheater, reheater, steam pipe, petrochemical heat exchanger pipe fittings.High temperature strength and high temperature plasticity; Excellent oxidation resistance and corrosion resistance; It has good organizational stability

317L Stainless steel color tube is more resistant to chemical corrosion than conventional chromium-nickel austenitic stainless steel such as alloy 304. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is low carbon grade or L grade, which is resistant to sensitization during welding and heat treatment

310S Stainless steel color tube is a 25Cr-20Ni series of high alloy stainless steel, high temperature oxidation resistance is excellent, suitable for the production of various furnace components, the highest temperature of 1200℃, continuous use of temperature 1150℃. Application: Material for furnace, material for automobile purification device.

309S Stainless steel color 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 color 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 color 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 color 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.
