Alloy Steel F91 Flanges are made up of carbon, manganese, silicon, sulfur, chromium and molybdenum. The 4% chromium content influences the corrosion resistance and the mechanical properties of the material. Multi Metals (India) is a leading manufacturer of the Alloy Steel F91 Flanges in different shapes, sizes and dimensions. The flanges are strong with 275MPa minimum yield strength and 485MPa minimum tensile strength.
The specification also has different standards such as ASME B16.47, B16.5 and others. The A182 F91 Alloy Steel flange comes in diameters ranging from ½ inches through 36 inches. There are different pressure classes ranging from 150 to 2500 and pressure numbers ranging from PN6 to PN64. The A182 F91 Flanges also range in face types such as ring type joint, flat face and raised face flanges. The functions of the flanges range differently as well.
The F91 grade flanges come in two different classes. The A182 F91 Class 2 flanges are less commonly used where the class 1 is the most used. There are slip on flanges, welded neck flanges, socket weld flanges and blind flanges that are used in different application requirements.
