What is ASTM A182 grade F53?

It is a forging material specification for 53 grade stainless steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.

ASTM A182 F53 flanges

ASTM A182 F53 flanges refer to flanges made from super duplex stainless steel 2507 (UNS S32750) by a hot forging process. It is listed in Material Group 2.8 according to ASME B16.5 and ASME B16.47. The pressure-temperature ratings for ASTM A182 F53 flanges are the same as that for other duplex stainless steels. The flanges shall not be used at temperatures over 600°F [315°C] since it may be subject to embrittlement after service at moderately elevated temperatures. ASTM A182 F53 flanges shall be solution annealed after forging at a temperature no less than 1880°F [1025°C], followed by water quenching.

Super Duplex Steel F53 (UNS S32750)

Technical Data Sheet

F53 is a high alloy duplex stainless steel. F53 has excellent resistance to pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types. Due to this F53 stainless steel is used primarily in highly corrosive conditions.
