What is Low Temperature Carbon Steel LF1 Flanges?

Low Temperature Carbon Steel LF1 Flanges are made with a controlled carbon content, along with manganese, silicon, and minimal sulfur and phosphorus, ensuring clean steel and robust toughness. Designed for cold environments, LF1 flanges maintain excellent impact resistance at temperatures as low as −20°C. This grade offers reliable yield and tensile strength, making it suitable for moderate-to-high pressure applications. Its refined microstructure enhances ductility, fracture resistance, and weldability, ensuring secure joint integrity even with temperature changes. The low carbon equivalent of LF1 supports smooth fabrication and long-term stability in chilled and low-temperature service conditions.
