SA 182 F91 Pipe Flange and ASME SA182 F91 Steel Blind Flanges manufacturer in India
A type of low alloy steel, grade F91 is referred to as a chrome moly alloy. Like other low alloy steel grades, the presence of elements as alloying content in these components is less. The content of chromium in the ASTM A182 F91 Flange ranges between 8% to 9.5%, making it one of the primary alloyants, with molybdenum between 0.85% - 1.05%. Though the content of molybdenum is maxed out at 1.05%, it follows closely behind chromium with regards to the amount. And the other elements included in the alloy by F91 Flanges Manufacturers include nickel, nitrogen, aluminum, niobium, silicon, and manganese - all of which are less than 0.6%. With molybdenum and chromium being more prominent in the alloy, it is referred to as chrome moly steel.
Steel alloys that contain higher amounts of chromium like the ASME SA182 F91 Material generally tend to have good resistance to atmospheric corrosion. In fact, this property is better than most carbon steel grades, especially in environments with elevated temperatures. The rate of corrosion is faster in such conditions, which is why the materials experience rapid degeneration. Another side-effect of prolonged exposure to thermal levels is a loss in mechanical properties like hardness and toughness. Molybdenum, silicon, and manganese included in the ASTM A182 F91 Class 3 Orifice Flanges offer the material better mechanical properties. These properties are a considerable improvement over regular carbon steel alloys. This alloy offers good weldability. The good weldability characteristics seen by this alloy have been attributed to the low content of carbon in the Alloy Steel A182 F91 Flange. Though alloying the alloy gives superior properties to the material, the use of heat treatments brings up these properties by a notch. Chrome Moly Grade F91 Blind Flange follows specification ASTM A182 for heat treatment details to optimize its mechanical properties.
