317L Stainless Seamless 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

309S Stainless Seamless Tube is free cutting stainless steel 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.

316L Stainless Seamless 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.

316 Stainless Seamless Tube due to the addition of Mo, its 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 solution state; Cold rolled product appearance gloss is good, beautiful.

321 Stainless Seamless 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 can be bent , no annealing after welding. It has excellent toughness even at low temperatures.

304 Stainless Seamless Tube 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.

304 Stainless Seamless Tube 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  Seamless Tube with 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  Seamless Tube is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components.
