Product origin:

Ottokunp, Sweden / Nippon Steel / Nippon Steel

Executive standard:

ASTM A240/ASME SA-240、ASTM A276、ASTM A182/ASME SA-182、ASTM A312/ASMES A312

Main ingredients:

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:

2507 dual phase steel density: 8.03g/cm3, melting point: 1300-1390 ℃, magnetism: None

Mechanical properties:

Tensile strength: σ B ≥ 795mpa, yield strength σ B ≥ 550MPa: elongation: δ ≥ 15%, hardness ≤ 310 (HB)

Corrosion resistance:

The high chromium and molybdenum content of 2507 duplex steel makes it have strong overall corrosion resistance to organic acids such as formic acid and acetic acid. 2507 dual phase 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 mixed with chloride ions. 904L is an alloy in austenitic state, which is specially used to resist pure sulfuric acid corrosion. 316L cannot be used in hydrochloric acid environment. It may suffer local corrosion or overall corrosion. 2507 dual phase steel is used in diluted hydrochloric acid environment and has strong resistance to pitting corrosion and interstitial corrosion.

Application fields:

Oil and gas industry equipment; Offshore platforms, heat exchangers, underwater equipment, fire-fighting equipment; Chemical processing industry, utensils and pipelines; Desalination, high-pressure RO equipment and submarine pipelines; Energy industry, such as power plant desulfurization and denitration FGD system, industrial scrubbing system, absorption tower; Mechanical parts (high-strength, corrosion-resistant and wear-resistant parts).

Supporting welding materials:

Er2594 welding wire and e2594 welding rod are selected for the welding of 2507 dual phase steel

Supply style:

Plates, strips, bars, wires, forgings, light rods, welding materials, flanges, etc. can be processed according to the drawing. Welcome to inquire
