SUS stainless steel pipe features and uses
SUS304 stainless steel pipe: It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, punching bending and other hot workability, no heat treatment hardening, no magnetic. Widely used in household products (1,2 categories of tableware), cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical equipment, building materials, chemicals, food industry, agriculture, and ships.
SUS304L stainless steel pipe: austenitic steel base, the most widely used, corrosion resistance and heat resistance, low temperature resistance and mechanical properties; single phase austenite structure, no heat treatment hardening phenomenon (non-magnetic, using temperature 196 - 800 °C).
SUS304Cu stainless steel tube: 2 - 17 - 7 nickel-chromium copper as basic austenitic stainless steel; good formability, especially drawing and good resistance to age cracking; 304 - the same as anti-corrosion.
SUS316 stainless steel pipe: Good corrosion resistance and high temperature strength, can be used under severe conditions, strain hardening and non-magnetic. Suitable for seawater and equipment, chemistry, dyes, paper, oxalic acid, fertilizer production equipment, photography, food industry, coastal facilities
SUS316L stainless steel pipe: plus steel cap (2 - 3%), therefore, good corrosion resistance and high temperature strength, resistance to intergranular corrosion than SUS316, high temperature creep strength. Can be used under harsh conditions, strain hardening and non-magnetic. Suitable for seawater and equipment, chemistry, dyes, paper, oxalic acid, fertilizer production equipment, photography, food industry, coastal facilities
SUS321 stainless steel tube: Ti added 304 steel, excellent resistance to intergranular corrosion; good high temperature strength and high temperature oxidation resistance, high cost. Heat-resistant materials, automobiles, aircraft exhaust pipes, boiler lids, pipes, chemical equipment, heat exchangers.
SUH409H stainless steel tube: processing performance, good welding performance, high temperature oxidation resistance, can withstand temperatures from room temperature to 575 °C. Widely used in automotive exhaust system.
SUS409L stainless steel tube: control steel C, N content, therefore, weldability, formability and excellent corrosion resistance, containing 11% of chromium, ferritic stainless steel at high temperature and room temperature BCC structure; filled with titanium, free at 750 °C oxidation and corrosion resistance.
SUS410 stainless steel pipe: martensitic steel, high strength, high hardness (magnetic); poor corrosion resistance, not suitable for use under severe corrosive environments; C content is low, processing performance is good, the surface can be hardened by heat treatment.
SUS420J2 stainless steel pipe: martensitic steel, high strength, high hardness (magnetic); poor corrosion resistance, poor processing and molding properties, good wear resistance, thereby enhancing heat treatment and mechanical properties. Widely used in tools, nozzles, valve plate feet, cutlery.
SUS430 stainless steel tube: low thermal expansion rate, type of formation and suitable for thermal equipment, good oxidation resistance, burners, household appliances, 2 kinds of cutlery, kitchen sink.
