SMO 254 Flange was first created for usage in seawater and other harsh conditions with high chloride concentrations. This grade is regarded as a very high-end austenitic stainless steel. This "ultra-austenitic" chemical composition's precise ratios of Cr, Ni, Mo, and N enable 31254 to combine impact toughness resistance to corrosion cracking with pitting and crevice corrosion resistance. The result is a strength almost two times greater than 300 series stainless steel.

Table Of Contents

Crevice corrosion and pitting resistance are both excellent in SMO 254 Flanges. SMO 254 Flanges have high resistance to corrosion in general. They strongly resist stress corrosion cracking and are stronger than typical austenitic stainless steel. SMO 254 Flanges have excellent weldability.

SMO 254 Flange can tolerate high temperatures and sustain strength under unstable conditions. Due to its high molybdenum and other elements, which enables SMO 254 Flange to be utilized successfully in various applications like Flue gas desulfurization and Chemical settings, this grade has expanded beyond its initial goal and overlapping into numerous industries.
