Material Summary
654SMO(EN 1.4652/UNSS32654) is a special stainless steel containing a high percentage of Nickel and Chromium containing 7% Molybdenum,which is the highest corrision restistance in the world.
It has a fairly high electrical conductivity among wrought superaustenitic stainless steels. In addition, it has the lowest thermal conductivity and very high tensile strength.
654SMo (S32654, 1.4652) super austenitic stainless steel features very good local corrosion resistance, good pitting resistance and good stress corrosion resistance under seawater, aeration, gap and low speed scouring conditions. It can be used as a good substitute to nickel-based alloys and titanium alloys. When it comes to high-temperature resistance or corrosion resistance, it is also superior to 904L and 254SMo.
