With a steadfast dedication to quality, reliability, and customer satisfaction, Quan Flanges and Plates caters to the oil, gas, petrochemical, power generation, and marine sectors around the globe.
Alloy Steel Orifice Flanges are made from carbon steel mixed with alloying elements like chromium (0.5–9%), molybdenum (0.2–1%), nickel, manganese, and vanadium. These components enhance the flanges’ strength, hardness, and resistance to corrosion, while the forging process improves their grain structure and toughness. In terms of mechanical properties, they boast a tensile strength ranging from 450–850 MPa, yield strength between 240–600 MPa, and an elongation of 20–30%. Their impressive hardness, impact resistance, and capacity to handle high-pressure and high-temperature conditions make them perfect for demanding industrial applications.
