Stainless Steel Alloy 254

Alloy 254, also known as Sandvik 254 SMO and UNS S31254, is a super austenitic stainless steel that is renowned for its exceptional resistance to pitting, crevice corrosion, fatigue corrosion, and stress cracking. The precise chemical composition of Alloy 254, which includes the following elements, contributes to these exceptional capabilities.

Fe (remainder) (remainder)

Cr 19.5-20.5%

Ni 17.5-18.5%

Mo 6-6.5%

Mn 1.0% max

Si 0.8% max

P 0.03% max

C 0.02% max

Due to its high chromium, nitrogen, and molybdenum content, Alloy 254 is stronger than the majority of austenitic stainless steels and approximately twice as strong as 300 series stainless steel. It is ideal for usage in a variety of applications, including:

Chemical synthesis

Applications of saltwater such as shipbuilding, marine products, and desalination

Gas and oil

Power generation

Paper and Pulp
