Chemistry

FERRALIUM 255 is 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.
