STM A182 F321H WNRF Stainless Steel Flanges Bridas
YUHONG supplies ASTM A182 F321H Stainless Steel Flanges.
ASTM A182 this specification covers forged low alloy and stainless steel piping components for use in pressure systems.
ASTM A182 F321H Flanges are made by bolting together two flanges with a gasket between them to provide a seal. It is an austenitic material which can be stabilized by the addition of Titanium and can be usually utilized for applications in temperatures up to 1,650 ℉. Also, F321 WN Flanges is an excellent choice for various applications ranging from oil refinery equipment to automative exhaust systems.
