Grade 254 SMO stainless steel strips are premium super austenitic stainless steel with a low carbon content that has been alloyed with molybdenum and nitrogen.
It has exceptional resistance to fatigue uniform corrosion, crevice corrosion stress cracking, and pitting.
The 254SMO stainless steel is also known as UNS S31254 and 1.4547.
Due to its fast work hardening rate and absence of sulfur, stainless steel strips grade 254 SMO are rather difficult to mill; however, using sharp tools, powerful machines, positive feeds, generous amounts of lubricant, and slow speeds tends to produce good machining results.
Due to the high presence of alloying elements, 254 SMO stainless steel strips exhibit outstanding homogeneous corrosion resistance. Because of the high alloying content of chromium and molybdenum, it can survive a variety of acids. Chromium, molybdenum, and nitrogen levels determine resistance to pitting and crevice corrosion.
These components are abundant in stainless steel strip 254 SMO, making it ideal for harsh situations like chlorinated seawater.
The concentration of nickel and molybdenum, in particular, increases with improved resistance to stress corrosion cracking.
This shows the excellent resistance to stress corrosion cracking of 254 SMO stainless steel strips.
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.
