Origin of Product：
Otokunp, Sweden /Metallurgy, Japan / Nippon Steel, Japan
Standard：
ASTM A240/ASME SA-240, ASTM A276, ASTM A182/ASME SA-182, ASTM A312/ASMES A312
Chemical Compositions:
% | C | Mn | Ni | Si | Cr | Mo | N |
MIN. | 4.5 | 21.0 | 2.5 | 0.08 | |||
MAX. | 0.03 | 2.0 | 6.5 | 1.0 | 24.0 | 3.5 | 0.20 |
Physical Properties:
Density | 8.03 g/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 makes it highly resistant to organic acids such as formic acid and acetic acid as a whole. 2507 duplex steel is also highly resistant to inorganic acids, especially those containing chlorides. Compared to 904L, which is an austenitic alloy, 2507 duplex steel is more resistant to dilute sulphuric acid mixed with chloride ions. 904L is an austenitic alloy and is specifically designed to resist corrosion by pure sulphuric acid. 316L cannot be used in hydrochloric acid environments where it may suffer from local or global corrosion. 2507 duplex steel is more resistant to pitting and gap corrosion when used in dilute hydrochloric acid environments.
Application：
Oil and gas industry equipment; offshore platforms, heat exchangers, underwater equipment, fire-fighting equipment; chemical processing industry, ware and pipeline industry; desalination, high pressure RO equipment and subsea pipelines; energy industry such as power plant desulphurisation and denitrification FGD systems, industrial scrubbing systems, absorption towers; mechanical components (high strength, corrosion resistant, wear resistant components).
Matching Welding Consumables：
ER2594 wire and E2594 electrode for the welding of 2507 duplex steel.
Supply Style：
Sheets, strips, bars, wire, forgings, bright bars, weldments, flanges, etc., according to the drawing
