ASTM A182 Gr F22 Alloy Steel Flanges Manufacturing Process

Flange Forging

Compared to cast flanges, forged flanges typically contain less carbon and are less likely to corrode. Forgings have superior mechanical qualities, a thicker structure, and a more streamlined shape.

Heat Treatment

The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds. The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds.

Forging Rolling

Roll forging is a forging technique that shapes a metal object by using opposing rolls. Although roll forging employs rolls to accomplish the desired material deformation, it is categorized as a metal forging procedure rather than a rolling procedure.

Rust Prevention

For steel flanges, conventional rust protection treatments include hot dip galvanizing, electro galvanizing (cold), varnish paint coating, black paint coating, black phosphating treatment, yellow (golden) paint coating, etc.

ASTM A182 F11 vs F22 vs F91

Chromium content separates these three grades and sets the ceiling on service temperature.

Property	F11	F22	F91
Chromium	1.00 to 1.50%	2.00 to 2.50%	8.00 to 9.50%
Molybdenum	0.44 to 0.65%	0.87 to 1.13%	0.85 to 1.05%
Max service temperature	550°C	595°C	650°C
Tensile strength, min	485 MPa	515 MPa	585 MPa
Yield strength, min	275 MPa	310 MPa	415 MPa
Pressure capability	Class 150 to 1500	Class 150 to 2500	Class 150 to 2500
Common applications	Steam piping, boiler headers	Hydrocrackers, reheaters	Supercritical steam headers
Relative cost	Lowest	Mid	Highest

Vanadium and niobium micro-alloying push F91 furthest, letting designers cut wall thickness above 600°C. Most refinery specifications still land on F22, which balances allowable stress against price and weldability.
