Kyoga Flanges, based in Bedok, Singapore, is a reliable manufacturer and supplier of Low Temperature Carbon Steel LF3 Flanges, engineered for extreme cold and pressure-critical applications. Designed to maintain toughness and strength at sub-zero temperatures, LF3 flanges ensure safe, crack-resistant performance where standard carbon steel becomes brittle. Precision-manufactured and strictly tested, Kyoga’s LF3 flanges deliver consistent quality, dimensional accuracy, and long service life. They are trusted across industries where low-temperature reliability, pressure integrity, and operational safety are absolutely essential.
Low Temperature Carbon Steel LF3 Flanges are composed of carbon, manganese, phosphorus, sulfur, and small amounts of other elements to enhance strength and ductility. With a carbon content up to 0.30%, they exhibit superior mechanical properties, including a yield strength of 275 MPa and tensile strength up to 515 MPa. LF3 flanges are specifically engineered to perform in low-temperature environments, offering excellent toughness and resistance to brittle fracture. Their advantages include high weldability, durability under extreme conditions, and reliability in critical industries like oil and gas, ensuring safe, long-term operations.
