Reputable Jakarta, Indonesia-based manufacturer and supplier Ismail Flanges specialises in premium Low Temperature Carbon Steel LF3 Flanges that are designed for cryogenic and low-temperature applications. LF3 flanges are widely used in the petrochemical, offshore, and LNG processing industries because of their remarkable toughness and structural integrity, which can withstand temperatures as low as -101°C. These flanges, which are made in compliance with ASTM A350 standards, guarantee excellent performance, robustness, and accurate fit in demanding applications. Offering dependable flange solutions throughout Indonesia and the global industrial market, Ismail Flanges is dedicated to quality, safety, and customer satisfaction.
To improve low-temperature performance, Low Temperature Carbon Steel LF3 Flanges are alloyed with silicon, carbon, manganese, and a higher proportion of nickel (up to 3.5%). These flanges have an elongation of about 22%, a tensile strength of 450–620 MPa, and a minimum yield strength of 240 MPa. LF3 flanges provide dependable weldability, machinability, and structural integrity, and they exhibit exceptional impact resistance at temperatures as low as -101°C. They are perfect for specialised low-temperature industrial systems because of their refined microstructure, which guarantees that they retain strength and ductility even under extreme cryogenic and sub-zero service conditions.
