Ismail Flanges provides precision-engineered flange solutions that are trusted in Southeast Asia and international markets, with a strong emphasis on quality control and customer satisfaction.
Carbon steel with a regulated composition of carbon, manganese, phosphorus, sulphur, and silicon is used to make Low Temperature Carbon Steel LF1 Flanges. At temperatures as low as -46°C, LF1 flanges, which are made for cryogenic service, provide exceptional impact resistance. They have an elongation of roughly 22%, a tensile strength between 380 and 550 MPa, and a minimum yield strength of 250 MPa. LF1 is a great option for applications involving low temperatures and dynamic loading because of the steel’s fine grain structure, which improves toughness, weldability, and structural integrity.
