Ferralium 255 VS 2507

Ferralium 255 and 2507 are both super duplex stainless steels with exceptional corrosion resistance and mechanical properties. However, there are certain distinctions between the two that could affect their utility in certain contexts.

Ferralium 255 (UNS S32550) is a duplex stainless steel with a balanced composition of chromium, molybdenum, and nitrogen that possesses high corrosion resistance and high strength. It has a high copper content, which makes it less likely to corrode in saltwater and other harsh situations. Marine engineering, offshore oil and gas exploration, and chemical processing are just some of the many uses for ferralium 255 due to its exceptional strength.

The super duplex stainless steel 2507 (UNS S32750) has higher concentrations of chromium, molybdenum, and nitrogen than Ferralium 255. The result is increased durability and resistance to corrosion. Ferralium 255 is commonly used in industries including chemical processing, oil and gas exploration, and pulp and paper production because of its high corrosion resistance and strength.

Overall, applications requiring for high strength and good corrosion resistance would benefit from Ferralium 255, while those calling for extraordinary corrosion resistance and mechanical strength would benefit most from 2507. Whether Ferralium 255 or 2507 is the better option depends on the details of the intended use.
