FAQ

1. What is ASTM A182 F304H flange?

ASTM A182 F304H flange is a forged stainless steel flange designed for high-temperature service.
Compared with standard 304 stainless steel, F304H offers improved creep strength and better heat resistance.

2. What does SORF flange mean?

SORF means Slip On Raised Face flange.
It is easy to install and widely used in low to medium pressure industrial piping systems.

3. What is the difference between 304 and 304H flange?

304H stainless steel contains higher carbon content than standard 304 stainless steel.
This improves high-temperature strength and makes it suitable for boilers, heat exchangers, and power plants.
