317L Stainless steel Hexagonal steel 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 Hexagonal steel is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance, because of the higher percentage of chromium and nickel, 310S has much better creep strength, can be continuously operated at high temperature, has good high temperature resistance.

309S Stainless steel Hexagonal steel containing sulfur, used for the main requirements of free cutting and high surface smoothness. 309s is a variant of 309 stainless steel with a lower carbon content for use where welding is required. The low carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may cause intergranular corrosion (weld erosion) in stainless steel in some environments.

316 Stainless steel Hexagonal steel It is a special corrosion resistant structure mainly used in food industry and surgical equipment. 316 stainless steel plasticity, toughness, cold denaturation, welding process performance is good, 316 high temperature strength is good, 316L high temperature performance is slightly worse, but corrosion resistance is better than 316, because the carbon content is low and contains 2%-3% molybdenum, improve the corrosion resistance of reducing salts and various inorganic acids and organic acids, alkali, salts, and high temperature strength.

316L Stainless steel Hexagonal steel 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 Hexagonal steel 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 gloss bar 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 Hexagonal steel 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 Hexagonal steel is a common material in stainless steel, the density is 7.93 g/cm³; The industry is also called 18/8 stainless steel, which means that it contains more than 18% chromium and more than 8% nickel; High temperature 800℃, with good processing performance, high toughness characteristics, widely used in industry and furniture decoration industry and food medical industry. However, it should be noted that food grade 304 stainless steel compared with ordinary 304 stainless steel, its content index is more strict.

301 Stainless steel Hexagonal steel 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.
