These flanges are made from a mix of carbon, manganese, silicon, phosphorus, and sulfur, with specific amounts of alloying elements tailored to the grade. This well-balanced chemical composition ensures excellent weldability, machinability, and strength. On the mechanical side, these flanges boast high tensile and yield strength, good impact resistance, and the ability to function reliably in both high and low temperatures. Processes like normalizing or quenching and tempering further boost their toughness and durability, making them ideal for heavy-duty service conditions. Carbon Steel A182 flanges consist mainly of carbon, manganese, phosphorus, sulfur, silicon, and trace elements, providing strength and durability. They have good mechanical properties, such as high tensile strength (485 MPa min), yield strength (250 MPa min), and hardness. The flanges have better weldability, toughness, and resistance to high pressure and temperature. Their benefits are cost savings, corrosion resistance, and flexibility in industrial use such as oil & gas, petrochemical, and power plant, which makes them suitable for critical piping applications.
