What is ASTM A182 F91 pipe fitting

the pipe fitting which material is astm a182 f91 we called it astm a182 f91 pipe fitting, which are used for the forged piping systems of high temperature service. astm a182 is the standard of forged or rolled alloy-steel pipe flanges, forged fittings,and valves and parts material, it indicates the materials properties of different kinds of alloy steel. f91 is one of the steel grade in this standard.f means forged,refer to the minimum yield strength. a182 f91 is the most common alloy steel pipe fittings material.

astm a182 f91 pipe fittings are forged,commonly used to be socketed or threaded connecting with the astm a213, a200,a336,a199,a369,a335 p91 steel pipes.
