ASME B16.5 1/2"-24" ASTM A182 F44 254SMO 1.4547 WN SO flange


1. 254SMO material brief introduction

254 SMO is an austenitic stainless steel designed for superior pitting and crevice corrosion. 254 SMO is ideal for high-chloride environments because of its high levels of chromium, molybdenum, and nitrogen. 254 SMO is often used where 316L or 317L has failed. 254 SMO is significantly stronger than the common austenitic grades, and it is also characterized by high ductility and impact strength.
