2507|S32750

Product Origin:Sweden Outokumpu/Nippon Metal/Japan Nippon Steel

Execution Standard:ASTM A240/ASME SA-240, ASTM A276, ASTM A182/ASME SA-182, ASTM A312/ASMES A312

Main Components:Carbon (C) ≤ 0.03, Manganese (Mn) ≤ 2.0, Nickel (Ni) 4.5～6.5, Silicon (Si) ≤ 1.0, Chromium (Cr) 21.0～24.0, Molybdenum (Mo) 2.5～3.5, Nitrogen (N) 0.08～0.20

Physical Properties:Density of 2507 duplex steel: 8.03g/cm3, Melting Point: 1300-1390 ℃, Magnetism: None

Mechanical Properties:Tensile Strength: σb ≥ 795Mpa, Yield Strength σb ≥ 550Mpa, Elongation: δ ≥ 15%, Hardness ≤ 310 (HB)

Corrosion Resistance:The higher chromium and molybdenum content of 2507 duplex steel give it strong resistance to organic acids such as formic acid and acetic acid. 2507 duplex steel also has strong corrosion resistance to inorganic acids, especially those containing chlorides. Compared with 904L, 2507 duplex steel has stronger corrosion resistance to diluted sulfuric acid containing chloride ions. 904L is an austenitic alloy specifically designed to resist pure sulfuric acid corrosion. 316L cannot be used in hydrochloric acid environments, as it may suffer from localized or general corrosion. 2507 duplex steel exhibits strong resistance to pitting and crevice corrosion in diluted hydrochloric acid environments.

Application Fields:Equipment in the petroleum and natural gas industry; offshore platforms, heat exchangers, underwater equipment, firefighting equipment; chemical processing industry, vessels, and piping industry; desalination, high-pressure RO equipment, and submarine pipelines; energy industry such as power plant flue gas desulfurization and denitrification (FGD) systems, industrial washing systems, absorption towers; mechanical components (high-strength, corrosion-resistant, wear-resistant parts).

Matching Welding Material:For welding 2507 duplex steel, ER2594 welding wire and E2594 welding rod are recommended.

Supply Style:Plates, strips, bars, wires, forgings, bright bars, welding materials, flanges, etc. Can be processed according to drawings. Feel free to contact us for inquiries.
