ASTM A182 / ASME SA-182 F304 heat Exchange Flanges with High Melting Point for High-Temperature Applications
ASTM A182 / ASME SA-182 F304 flanges are forged flanges made of F304 grade stainless steel that conform to the ASTM A182 / ASME SA-182 standard. This material is commonly used for high-performance flanges in demanding applications.
ASTM A182 / ASME SA-182 covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and components for high-temperature applications.
F304 offers excellent corrosion resistance in a wide range of atmospheric, chemical, and food/beverage environments.
Heater flanges are particularly common components in the following applications:
Fired heaters and boilers: Used to connect piping conveying hot fluids (oil, gas, steam, water) within or outside the heater structure.
Heat exchangers: Used to connect piping to the shell/tube side.
High-temperature process piping: Used in refineries, chemical/petrochemical plants, and power plants (fossil fuel and nuclear).

ASTM A182 F304 Flange Application
Key Applications:
Oil and gas refining (piping, heaters, reactors)
Chemical and petrochemical processing
Power generation (fossil fuel boilers, specialized steel grades for
nuclear power)
Fired heaters and boilers
Heat exchangers
High-temperature steam systems
Food and beverage processing (hygienic applications typically use
304L)
Cryogenic systems (due to its good toughness at low temperatures)
