We are professional UNS S32550/A182-F61/1.4507/Ferralium 255 Forged Forging Oil measurement valve Spool Ultrasonic flow meter bodies Body from china
FERRALIUM 255 is a cost effective alternative to materials such as the nickel alloys, 20 type alloys, brass and bronze. Marine environments have long been the domain of admiralty bronze. Alloy 255 is replacing admiralty bronze, and the nickel alloys, in offshore platforms, deck hardware, rudders and shafting.
Alloy 255 is also making inroads in "borderline" corrosion applications where the nickel alloys and high performance alloys have been used but may not have been absolutely necessary. In some instances, it has even been used to replace high performance Ni-Cr-Mo-F-Cu alloys in the phosphoric acid industry.
Valves, pumps, shafts, marine environments, Applications in down-hole, waste water, polycarbonate production, and demineralized water production.
Chemistry
FERRALIUM 255's high critical pitting temperature and high critical crevice temperature provide more resistance to pitting and crevice corrosion than lesser alloyed materials. The alloy's very high yield strength combined with good ductility allows lower wall thicknesses in process equipment.
