Based in Mumbai, India, Harsh Flanges is a top producer and supplier of LF3 Flanges made of Low Temperature Carbon Steel (LTCS), which are ideal for applications requiring temperatures below freezing. We offer robust and dependable flange solutions for demanding environments and are renowned for our precision engineering, consistent quality, and adherence to international standards. Our LF3 flanges are well known for their exceptional weldability, toughness, and low-temperature resistance to brittle fracture. With an emphasis on long-term performance and safety, Harsh Flanges provides fast delivery and customised solutions to customers in a variety of industries, including petrochemicals, power generation, and oil and gas.
Carbon, manganese, silicon, and trace amounts of nickel (up to 3.25%) make up the majority of LF3 Low Temperature Carbon Steel Flanges, which increases their durability in low-temperature settings. At temperatures as low as -50°C, these flanges demonstrate exceptional impact resistance, a minimum yield strength of 240 MPa, and a tensile strength ranging from 415 to 585 MPa. Superior weldability, ductility, and resistance to brittle failure are guaranteed by their fine-grained structure. Because of these characteristics, LF3 flanges are perfect for low-temperature and cryogenic service conditions in demanding applications.
