UNS S32654 Stainless Steel

Equivalent Grades: UNS S32654 (Alloy 654), EN 1.4652, ASTM UNS S32654, X1CrNiMoCuN24-22-8, 654 SMO

UNS S32654 (1.4652, 654SMO) is a type of special stainless steel containing a high percentage of Nickel and Chromium, containing 7% molybdenum, and very high Nitrogen, High mechanical strength. 654SMO (1.4652, UNS S32654) is stainless steel with the highest corrosion resistance in the world. It has a fairly high electrical conductivity among wrought super austenitic stainless steel. In addition, it has a fairly low thermal conductivity and moderately high ductility.

Useful for e.g. pressurized and erosive systems handling chlorinated seawater at higher temperatures, plate heat exchangers, and flue gas cleaning applications.
