Description
654SMO stainless steel is a super austenitic stainless steel which contains 23% nickel, 25% chromium and 7% molybdenum.
The nitrogen content of 654SMO stainless steel is twice as high as 254SMO grade, and its strength is higher than 904L stainless steel and 254SMO stainless steel.
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.
