254SMO® Stainless Steel Strip

Introductions

What Is 254SMO® Stainless Steel Strip

254SMO® stainless steel strip is an austenitic stainless steel strip.

Due to the high molybdenum content, it has extremely high resistance to pitting corrosion and crevice corrosion.

This grade of stainless steel strip was developed and designed for containing halide application such as seawater. 254SMO® is a registered trademark of Outokumpu OYJ.

254SMO® stainless steel strip also has good uniform corrosion resistance especially in acids containing halide. This steel is superior to ordinary stainless steel.

It has good resistance to pitting corrosion (PI≥40) and good stress corrosion resistance under the conditions of sea water application and low-speed erosion.

It is a substitute material for special alloy strips and titanium strips.

What’s more, it has better high temperature resistance and corrosion resistance, which is irreplaceable for 304 stainless steel strip.
