Alloy Steel Forged Flanges are top-notch components crafted through a forging process that guarantees exceptional mechanical strength, structural integrity, and long-lasting durability. These flanges are made from alloy steels infused with elements like chromium, molybdenum, and nickel, making them capable of withstanding extreme pressure, high temperatures, and harsh corrosive environments. Uday Flanges, a well-respected manufacturer and supplier based in Dubai, UAE, provides a comprehensive selection of Alloy Steel Forged Flanges that meet international standards such as ASTM A182, ASME B16.5, and DIN. You’ll find these flanges widely utilized in power generation, petrochemical facilities, oil & gas systems, and demanding industrial applications.
Typically, Alloy Steel Forged Flanges are produced from grades like ASTM A182 F1, F5, F9, F11, F22, and F91. These flanges are enriched with alloying elements such as chromium (up to 12%), molybdenum, and nickel, which boost their strength, toughness, and heat resistance. The forging process refines the grain structure, enhancing fatigue resistance and overall mechanical properties. Their tensile strength ranges from 450 to 690 MPa, while yield strength falls between 240 and 520 MPa, depending on the specific grade. These flanges excel in resisting thermal fatigue, creep, and corrosion, making them perfect for demanding pressure system conditions.
