Refer Alloy Steel F91 Forged Elbow Mechanical Properties And SA 182 Gr F91 Blind Flange Equivalent.

Compared to conventionally used carbon steels, the ASTM A182 F91 Flange is more expensive. Yet, the cost factor could be justified with regards to its mechanical properties which are much higher than carbon steel. Another important characteristic of the Alloy Steel F91 Forged Elbow is that these fittings have much better corrosion resistance properties as well. The alloy of a conventional carbon steel fitting is an alloy of just carbon and iron. On the other hand, the alloy used in the manufacture of ASME B16.5 A182 F91 Cl2 RTJ Flanges must conform to the ASTM A182 specification with regards to the alloyants used in the metal. Hence, the chemistry of alloy steel and stainless steels may contain a combination of the following elements - carbon, chromium, columbium, manganese, phosphorus, silicon, nickel, molybdenum and titanium.

What Is ASTM A182 F91 Flange?

Depending on the alloy used to produce the A182 F91 Alloy Steel Slip On Flanges, the manufacturer may use the relevant elements to make the alloy. The addition of different alloyants results in different results. The addition of nickel to the alloy of ASTM A182 F91 Forged Fitting increases the ability of the alloy to withstand elevated temperatures. On the other hand, the presence of chromium in the alloy of SA 182 Gr F91 Blind Flange in a percentage of more than 11% of its total weight results in the formation of a protective self-repairing passivated oxide layer, thus effectively becoming resistant to oxidation corrosion.
