Technical data

Super duplex stainless steels offer excellent impact strength, thermal conductivity, a low coefficient of thermal expansion, and excellent resistance to chloride stress corrosion. The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevices, and corrosion. Alloy 2507 is the most frequently used super duplex stainless steel. It contains 25% chromium, 4% molybdenum, and 7% nickel, a design intended for demanding applications
that require exceptional strength and corrosion resistance.


Super duplex stainless steels are used in the oil and gas, chemical processing, and power industries. Equipment fabricated using super duplex stainless steels includes offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems, vessels, piping, FGD systems, utility and industrial scrubber systems, absorber towers, and ducting. Other applications include desalination plants, seawater piping and high pressure RO plants.

We machine and weld various grades of super duplex stainless steel
