With its main office in Jakarta, Indonesia, Ismail Flanges is a reputable producer and supplier of Low Temperature Carbon Steel LF5 Flanges, which are ideal for demanding uses in cryogenic and sub-zero conditions. These flanges are perfect for use in chemical processing facilities, offshore platforms, refineries, and LNG, among other industries where low temperature performance is crucial. LF5 flanges provide exceptional mechanical strength, impact resistance, and sealing performance and are engineered to meet strict international standards. Ismail Flanges is dedicated to offering well-made, precisely engineered products that provide enduring dependability for demanding industrial systems that operate at low temperatures.
The main constituents of Low Temperature Carbon Steel LF5 Flanges are carbon, silicon, nickel, manganese, and trace amounts of sulphur and phosphorus. At temperatures as low as -75°C, this alloy composition is designed to provide increased toughness and ductility. The flanges have an elongation of about 22%, a tensile strength between 485 and 655 MPa, and a minimum yield strength of 275 MPa. Because of their exceptional impact resistance, weldability, and machinability, LF5 flanges are appropriate for harsh service settings where thermal resilience and structural integrity are essential.
