On the characteristics and uses of stainless steel sheet
The following are the major characteristics and uses of stainless steel sheet:
SUS304: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, bending and other thermal processing is good, no heat treatment hardening, non-magnetic. Widely used in household appliances ( 1, 2 types of tableware ), cabinets, indoor pipelines, water heaters, boilers, bath, auto parts, medical equipment, building materials, chemical, food industry, agriculture, ship parts.
SUS304L: basic steel austenite, the most widely used applications; corrosion resistance and heat resistance; low temperature strength and excellent mechanical properties; single-phase austenite, no heat treatment hardening ( non magnetic, the use of temperature -196--800℃).
SUS304Cu: with 17Cr-7Ni-2Cu as the basic composition of the austenite stainless steel; excellent formability, especially drawing and anti aging crack resistance; - corrosion resistance and 304 the same.
SUS316: corrosion resistance and high temperature strength is particularly good, can be used in harsh conditions, work hardening is good, no magnetism. Suitable for water equipment, chemical, papermaking, dye, oxalic acid, fertilizer production equipment, photographic, food industry, coastal facilities
SUS316L: Steel by adding Mo (2-3%), so the corrosion resistance and high temperature strength of good; SUS316L carbon content lower than SUS316, therefore, the resistance to intergranular corrosion resistance than SUS316 excellent high-temperature creep strength is high. In the harsh conditions of use, work hardening is good, no magnetism. Suitable for water equipment, chemical, papermaking, dye, oxalic acid, fertilizer production equipment, photographic, food industry, coastal facilities
SUS321: on 304 steel by adding Ti, so the resistance to intergranular corrosion resistance; high temperature strength and high temperature antioxidation quality; the high cost, processing of SUS304 worse than. Heat resistant materials, automobile, vehicle exhaust pipe, boiler cover, pipelines, chemical equipment, heat exchanger.
SUH409H : processing performance, good welding performance, high temperature oxidation resistance performance is good, can withstand temperatures ranging from room temperature to 575℃. Widely used in automotive exhaust gas exhaust system.
SUS409L: control of steel in C and N content, the weldability, formability and excellent corrosion resistance; including 11%Cr, high temperature and normal temperature with the structure of BCC ferritic stainless steel; due to fill in Ti, 750℃air oxidation and corrosion resistance.
SUS410: martensitic steel has high strength, representative, high hardness ( magnetic ); the poor corrosion resistance, not suitable for severe corrosive environment; C content low, good processing performance, through heat treatment can make the surface hardening.
SUS420J2: martensitic steel has high strength, representative, high hardness ( magnetic ); poor corrosion resistance, machinability, good wear resistance; can be heat treated to improve the mechanical properties of. Widely used in machining tools, pipe, valves, steel ruler, tableware.
SUS430: low thermal expansion coefficient, forming and oxidation resistance good applicable to heat apparatus, burner, household electrical appliances, 2 types of tableware, kitchen sink. Low price, good processing is the ideal replacement for the SUS304; anti miles good corrosion resistance, the typical non heat treatment hardening of ferritic stainless steel.
