Alloy Steel Flanges are tough, high-strength components crafted for demanding environments where high pressure, high temperatures, and corrosive conditions are the norm. These flanges are made from a blend of materials that include elements like chromium, molybdenum, nickel, and manganese, giving them an edge in mechanical strength, wear resistance, and corrosion resistance when compared to standard carbon steel. Uday Flanges, a prominent manufacturer and supplier based in Dubai, UAE, offers a diverse selection of Alloy Steel Flanges that meet global standards such as ASTM A182, ASME B16.5, and DIN. Perfect for critical applications in oil & gas, power generation, petrochemical, and refinery systems, these flanges are built to last and perform reliably under extreme conditions.
Typically, Alloy Steel Flanges are produced from grades like ASTM A182 F1, F5, F9, F11, F22, and F91. These materials are enriched with alloying elements such as chromium (up to 12%), molybdenum (up to 1.25%), and nickel, which significantly boost their tensile strength (450–690 MPa) and yield strength (240–520 MPa). They excel in creep resistance, high-temperature stability, and are resistant to oxidation and thermal fatigue. Heat treatment processes like normalization, quenching, and tempering can enhance their mechanical performance. Their robust characteristics make them perfect for applications involving superheated steam, high-pressure fluids, and exposure to corrosive chemicals.
