Heat treatment: Heat preservation between 1000-1052ºC for 1-2 hours, rapid air cooling or water cooling.
Mechanical properties: Tensile strength: σb≥795Mpa, yield strength σb≥550Mpa: elongation: δ≥15%, hardness ≤310 (HB)
Corrosion resistance and main use environment: The high chromium and molybdenum content of 2507 duplex steel makes it have a strong ability to resist the overall corrosion of 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 mixed with chloride ions. 904L is an austenitic alloy designed to resist pure sulfuric acid corrosion. 316L can not be used in hydrochloric acid environment, it may be subjected to local corrosion or overall corrosion. 2507 two-phase steel is used in diluted hydrochloric acid environment, with strong resistance to point corrosion and resistance to backlash corrosion.
Matching welding materials and welding process: 2507 two-phase steel welding selection of ER2594 wire and E2594 electrode, welding material size Φ1.6, 2.4, 2.5, 3.2, 4.0, origin: Austria GG, Sweden AVESTA and Italy TFA, welding process and instructions welcome to call for.
Applications: oil and gas industry equipment; Offshore platforms, heat exchangers, underwater equipment, fire fighting equipment; Chemical processing industry, utensils and pipes industry; Desalination, high pressure RO equipment and submarine pipeline; Energy industry such as power plant desulfurization and denitrification FGD system, industrial washing system, absorption tower; Mechanical parts (high strength, corrosion resistance, wear resistance parts).
