What Is ASTM A182 F304 Insert?

 

ASTM A182 F304 Insert is a forged stainless steel pipe fitting made from grade F304 (the forged version of 304 stainless steel), and is typically used as a socket weld fitting in high-pressure piping systems.

 

Definition & Description

  • Insert: A short-length socket weld fitting used to connect pipe ends by inserting them into the socket and welding around the outside.

  • Socket Weld: A type of welded joint where the pipe is inserted into a recessed area of the fitting, creating a strong, leak-proof connection ideal for high-pressure and high-temperature service.

  • Material: ASTM A182 F304 — forged austenitic stainless steel (similar to 304 stainless steel), offering excellent corrosion resistance, weldability, and mechanical strength.
