Features of 2507 Duplex Stainless Steel Plate

Corrosion resistance
1. General corrosion
The high chromium and molybdenum content of SAF 2507 makes it have strong resistance to organic acids such as formic acid and acetic acid. SAF 2507 alloy has strong resistance to inorganic acids, especially those containing chlorides. Anti-corrosion ability.
Compared with 904L, SAF2507 has stronger corrosion resistance to diluted sulfuric acid mixed with chloride ions.904L is an austenitic alloy, which is specially used to resist the corrosion of pure sulfuric acid.
316L grade cannot be used in hydrochloric acid environment, it may suffer local corrosion or overall corrosion. SAF2507 can be used in diluted hydrochloric acid environment and has strong resistance to spot damage and crevice corrosion.
2. Intergranular corrosion
The lower carbon content of nSAF 2507 greatly reduces the risk of carbide precipitation in the intergranular during heat treatment. Therefore, this alloy has a strong ability to resist intergranular corrosion related to carbides.
3. Stress corrosion cracking
The duplex structure of SAF 2507 gives it strong resistance to stress corrosion cracking. Due to its higher alloy content, the corrosion resistance and strength of SAF 2507 are better than 2205.
Cracks are almost inevitable in construction and other aspects, which makes stainless steel more susceptible to corrosion in a chloride environment. SAF 2507 has a strong ability to resist crack corrosion. SAF 2507's isocorrosion curve in sulfuric acid containing 2000ppm chloride ion 0.1 mm/year; isocorrosion curve in hydrochloric acid 0.1 mm/year.
Mechanical properties: SAF 2507 has high compressive strength, impact strength, low thermal expansion coefficient and high thermal conductivity. These characteristics are suitable for many structural parts and mechanical parts. SAF 2507 has high impact strength and is not suitable for long-term placement In a temperature environment higher than 570°F, this may weaken its toughness. Tensile strength: σb≥730Mpa; Elongation: δ≥20%

Product & Application

0025Ni7Mo4N steel is a super duplex stainless steel developed in Sweden in recent years. The commercial grade is SAF2507. It is mainly used in harsh media, especially in chlorine-containing environments, such as seawater. The balanced composition design of high chromium, high aluminum and high nitrogen in steel makes the steel highly resistant to stress corrosion, pitting and crevice corrosion, and it is also very low in organic acids and a certain range of inorganic acids. The corrosion rate. Some countries have been included in the standard, such as the United States' UNSs32750, Germany's DNxCNiMON2574, Sweden's Ss2328 and so on. The American Society of Mechanical Engineering has also recognized that 2507 steel is suitable for ASME standard boilers and pressure vessels, as well as chemical plants and oil refineries piping standards.
