Alloy Steel Flanges are strong and durable components used to connect pipes, valves, pumps, and other equipment in piping systems. Made by blending carbon steel with alloying elements like chromium, nickel, molybdenum, and vanadium, these flanges offer excellent mechanical strength, resistance to corrosion, and durability under high pressure and temperature. They are manufactured in various types such as slip-on, weld neck, socket weld, and blind flanges to suit different industrial needs. Known for their long service life and reliability, Alloy Steel Flanges are widely used in industries like oil & gas, power generation, chemical, and petrochemical plants.
Alloy Steel Flanges are composed of carbon (0.15%–0.30%), chromium (0.5%–5%), molybdenum (0.2%–1%), nickel (0.5%–3%), and small amounts of manganese and silicon. This combination improves hardness, toughness, and resistance to wear and heat. They generally have a tensile strength of 450–850 MPa and yield strength ranging from 250–600 MPa, depending on the grade. Alloy Steel Flanges also display good impact resistance, excellent weldability, and the ability to withstand high stress and pressure. Their mechanical stability makes them reliable for demanding environments in process and structural industries.
