654SMO® Stainless Steel Strip

Introductions

What Is 654SMO® Stainless Steel Strip

654SMO® stainless steel strip is a super austenitic stainless steel strip which contains 23% nickel, 25% chromium and 7% molybdenum.

Its corrosion resistance is equivalent to that of the best nickel-base alloys. 654SMO® is a registered trademark of Outokumpu OYJ.

The nitrogen content of 654SMO® stainless steel is twice as high as 254SMO® grade, and its strength is higher than 904L stainless steel strip and 254SMO® stainless steel strip.

654SMO® super austenitic stainless steel strip has very good local corrosion resistance.

It has good pitting corrosion resistance and good stress corrosion resistance under the conditions of sea water, aeration, crevices, and low-speed erosion.
