ASTM A182 F9 Flanges Manufacturer

ASTM A182 / A182M – Standard Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, Valves and Parts for High-Temperature Service

F9 refers to a forged material grade with 9 % Cr

ASTM A182 F9 is a forging material grade of so-called “9-Chrome 1-Moly” material ,the same grade with the piping grade ASTM A335 P9 Seamless Pipes,and ASTM A234 WP9 for Pipe fittings.

ASTM A182 F9 Heat Treatment

After hot working, forgings must be cooled to a temperature below 1000∘F(538∘C) before heat treatment

ASTM A182 requires that all F9 components be heat treated after final forging to ensure proper mechanical properties for high-temperature and high-pressure applications.

Annealing

Normalized and Tempered (N+T)

ASTM A182 F9 FlangesTesting Requirements

Mandatory Tests (per ASTM A182 & A961):
