Description:
254SMo is a 18% Ni, 20% Cr, 6% Mo super austenitic stainless steel grade with 0.2% nitrogen additions, particularly designed to be cost effective. The 18% nickel and 0.7% copper additions combined with the chromium and molybdenum additions enhance the performance of the steel in many corrosive solutions encountered for example in chemical and petrochemical processes or chloride containing solutions. The alloy is also seawater resistant and has extensively been used in offshore applications.
