Product Overview

Alloy 254 SMO is a high-end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. It demonstrates outstanding resistance to pitting, crevice corrosion, stress cracking, and corrosion fatigue. With strength nearly twice that of 300 series stainless steel, it offers high ductility and impact strength while maintaining excellent corrosion resistance in high chloride environments.

Corrosion Resistance

Excellent resistance to pitting and crevice corrosion due to high chromium, molybdenum, and nitrogen content
Very low carbon content minimizes risk of carbide precipitation during heating
Superior resistance in chloride-containing waters, suitable for prolonged seawater exposure
