347H Stainless steel black rod 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 black rod 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 black rod 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 black rod can withstand 980℃ below repeated heating; High high temperature strength; It has high oxidation resistance; It has high anti-carburizing performance

316 Stainless steel black rod corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in harsh conditions; Excellent work hardening (non-magnetic); Excellent high temperature strength; Non-magnetic in solid solution state; Cold rolled products have good appearance gloss and can be used under harsh conditions. Can be used for seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment.

316L Stainless steel black rod 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 black rod exhibits high strength, resistance to oxidation peeling and subsequent stability against aqueous solution corrosion in a temperature range up to approximately 900 degrees Celsius. 321 Stainless steel black rod 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 black rod 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 black rod is one of the most popular stainless steel cold rolled sheet 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.
