A182 F51 2205 S31803 flange ring with extreme corrosion resistance and strength
Due to the material composition, the strength and the corrosion resistance, these flanges are used in a variety of applications.
ASTM A182 includes several grades of low alloy steels and ferritic, martensitic, austenitic, and ferritic-austenitic stainless steels based on design and service requirements. The ASTM A182 F51 flanges with hub shall be manufactured by a hot forging process, in which the material shall be forged as close as practicable to the specified shape and size. 2205 duplex stainless steelis a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking.
