Duplex 2507 is super stainless steel designed for critical applications which need excellent strength and corrosion resistance. It contains up to 26% chromium, 8% nickel and 5% molybdenum, which leads to outstanding resistance to pitting, crevice and general condition corrosion.
Duplex 2205 has less element content than 2507 and the overall corrosion resistance is lower.
Super duplex 2507 has outstanding resistance to chloride stress corrosion cracking. While it can keep high thermal conductivity and low thermal expansion coefficient. It is also highly resistant to organic acids like formic and acetic acid.
904L stainless steel is designed for resistance of pure sulfuric acid. However, when handling with dilute sulfuric acid mixed with chloride ions, 2507 outperforms 904L in corrosion resistance.
2507 can also be used in dilute hydrochloric acid, which will severely corrode 316L stainless steel.
2507 super duplex stainless steel is primarily used in seawater related applications, chemical processing and other chloride environment.
