Fajar Metals stands out as a leading manufacturer and supplier of top-notch metal components right from Jakarta, Indonesia, with a special focus on Duplex Steel S31803 Forged Fittings. Known for their durable and precisely crafted products, the company caters to industries that require exceptional strength, corrosion resistance, and longevity. By leveraging cutting-edge forging technology and maintaining rigorous quality control, Fajar Metals creates forged fittings that adhere to international standards, ensuring reliable performance even in high-pressure and corrosive settings. They serve various sectors, including oil & gas, petrochemical, marine, and power generation, providing a dependable supply, technical know-how, and customer-centric service both locally and globally.
Duplex Steel S31803 Forged Fittings are made up of approximately 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, all balanced with iron. This unique alloy boasts a dual-phase austenitic-ferritic structure, which delivers outstanding corrosion resistance and mechanical strength. These fittings have a tensile strength ranging from 620 to 880 MPa, a yield strength of 450 MPa, and an elongation of at least 25%. They are particularly resistant to pitting, crevice corrosion, and chloride stress corrosion cracking. Their exceptional mechanical integrity and fatigue strength make them perfect for high-pressure systems and harsh chemical environments.
