F53 Super Duplex Stainless Steel

Super duplex stainless steel (UNS S32750 / 2507) with a balanced austenitic-ferritic microstructure. With a PREN above 40 it offers superior resistance to pitting, crevice corrosion and chloride stress-corrosion cracking versus F51, together with roughly double the yield strength of standard austenitic grades.
