Alloy Steel Flanges are composed of a blend of carbon steel with various alloying elements such as chromium, molybdenum, nickel, and vanadium. This composition enhances their strength, hardness, and resistance to corrosion and heat. Mechanically, they offer high tensile strength (typically 620–850 MPa), yield strength (up to 450 MPa), and excellent fatigue resistance. The advantages of alloy steel flanges include improved wear resistance, high-temperature stability, and superior toughness, making them ideal for use in demanding industries like petrochemical, oil and gas, power generation, and heavy manufacturing.
