Long term sale of high end double phase steel 2507 sheet tape, product name: 2507 biphase steel \UNS S32750
International general term: SAF 2507, UNS S32750, NAS 74N, W.-Nr. 1.4410
Execution standards: ASTM A240/ASME SA-240, ASTM A276, ASTM A182/ASME SA-182, ASTM A312/ASMES A312
Main ingredients: carbon (C = 0.03), Mn (Mn) = 2, Ni (Ni) 4.5 ~ 6.5, silicon (Si) = 1, Cr (Cr) 21 ~ 24, 2.5 ~ 3.5 mo (Mo), nitrogen (N) from 0.08 to 0.20
Physical properties: 2507 biphase steel: melting point: 1300-1390 C, magnetic: no
Heat treatment: heat preservation for 1-2 hours between 1000-1052 degrees C, fast air cooling or water cooling.
Mechanical properties: tensile strength: B = 795Mpa, B = 550Mpa: yield strength elongation: 8 = 15%, the hardness is less than or equal to 310 (HB)
Corrosion resistance and main application environment: 2507, the high chromium and molybdenum content of dual phase steel make it strong corrosion resistance to organic acids such as formic acid and acetic acid. 2507 biphase steel also has strong corrosion resistance to inorganic acids, especially those containing chlorides. Compared with 904L, 2507 biphase steel has a stronger corrosion resistance to the diluted chloride ion sulphuric acid. 904L is an alloy of austenite state, which is specially designed for anti - pure sulfuric acid corrosion. 316L can not be used in hydrochloric acid environment, it may be subjected to local corrosion or overall corrosion. 2507 biphase steel is used in dilute hydrochloric acid environment with strong resistance to point corrosion and anti gap corrosion. Storage situation of Wuxi and Swiss Stainless Steel Co., Ltd.: 2507, dual phase steel stock spot size has 2mm-30mm, 2507 dual phase steel bar and 2507 dual phase steel pipe fittings and other can be customized according to customer requirements. Domestic Baosteel, Taiyuan Steel, Zhang Pu, Jiuquan Steel and so on, imported: Japan, Sweden. Provide the material certificate of the original factory. Another part of the 2507 stainless steel bar and 2507 stainless steel pipe are sold well, quality and quantity is guaranteed, welcome to buy, super duplex steel 2507 application area: oil and natural gas industrial equipment; offshore equipment, heat exchanger, food industry, mechanical parts and other high requirements areas.
