The workability of FERRALIUM 255 alloy added to its excellent mechanical, physical and chemical properties, making it super stainless steel indeed. For it can be cast, forged, rolled, and welded.
This fan impeller provides an example of its versatility. The boss is cast, and the blades are rolled and shaped from the plate then welded to the blade roots cast in the boss. The side plates are also of the plate, the conic-shaped segments being welded together then the boss and blades. The whole thing is 71” in diameter and weighs, as shown, nearly 1 ½ ton.
It forms part of an inert gas fan in a wet SO2 scrubber and runs at 1470 rpm. The combination of gases and other corrosive ingredients produced creates an atmosphere conducive to stress corrosion to which FERRALIUM 255 (UNS S32550, Alloy 255, DIN 1.4507, ASTM F61) has excellent resistance. Built by Davidson & Co. Ltd., of Belfast, the giant fan is installed in the non-ferrous smelting plant of Commonwealth Smelting Ltd. at Avonmouth.
