UNS S31254/F44 is a 6Mo super austenitic stainless steel with a density of 8.24 g/cm3 and a typical PREN of 42 ~ 44, ensuring that it is designed for impact toughness, resistance to chloride crevice corrosion, stress corrosion cracking and pitting. It combines good mechanical strength and high ductility to provide excellent corrosion resistance in a variety of environments. In the annealed state, the yield strength exceeds 44 KSI (300Mpa).
