Carbon Steel A350 LF2 Flanges are crafted from low-alloy carbon steel, which includes carbon (≤0.30%), manganese, phosphorus, sulfur, silicon, and trace elements. They undergo normalization and tempering to enhance their impact toughness. Typically, the tensile strength falls between 485–655 MPa, with a yield strength of about 250 MPa. These flanges exhibit remarkable ductility and notch toughness even at temperatures as low as -46°C (-50°F), ensuring safety in frigid environments. The fine-grain microstructure achieved through controlled heat treatment boosts fatigue resistance and structural integrity, making them a dependable choice for pressure-containing applications in cold service.
