The mention of specification ASTM A182 would be an apt indicator that the alloy used in its manufacture could be categorised as a high temperature steel grade. Apart from being well equipped to deal with high temperature applications, the ASTM A182 F91 Flanges are components that are produced by either forged or rolled alloy grades. Which means the mechanical properties of these forged alloy steel grades tend to be much higher. In the case of flanges, one must consider an increase in the fatigue and impact resistance of this alloy. This is because when the alloy used to make ASME SA182 F91 WNRF Flange has been forged, the process not only refines but also directs the grain flow according to the shape or the form of the piece.

Moreover, the forging process mentioned in the specification for the Alloy Steel F91 Flanges is required to conform to several variables in its process such as the kind of heat treatment used on the alloy, austenitizing/solution temperature along with cooling media, and quenching. As typical of any ASTM specification, the specified ASTM A182 Grade F91 Flange is produced by manufacturers keeping in accordance with the requirements mentioned there. For instance, aside from the chemical composition requirements, it has been mandated that the ASTM A182 Gr F91 Slip On Flanges undergo certain tests to check the conformance of values such as tensile strength, yield strength, elongation as well as Brinell hardness.
