Fajar Metals, a well-respected industrial manufacturer and supplier located in Jakarta, Indonesia, is known for providing top-notch metal solutions across various sectors. One of their standout products is the Duplex Steel Valves, designed for optimal performance in harsh, corrosive, and high-pressure settings. Crafted with precision and rigorous quality checks, these valves blend the advantages of austenitic and ferritic stainless steels, ensuring remarkable strength and resistance to stress corrosion cracking. Fajar Metals caters to industries like oil and gas, petrochemicals, water treatment, and marine engineering. With its strategic location and dedication to quality, Fajar Metals has become a reliable source for trustworthy valve technology both in Indonesia and internationally.
Duplex Steel Valves from Fajar Metals are generally made from grades such as UNS S31803 or S32205, containing around 22% chromium, 5–6% nickel, 3% molybdenum, along with trace amounts of nitrogen and manganese, with iron making up the rest. These dual-phase (austenitic-ferritic) alloys provide outstanding corrosion resistance and impressive mechanical strength. The valves boast a tensile strength ranging from 620 to 800 MPa, a yield strength of about 450 MPa, and an elongation of 25 to 30%. They excel in aggressive environments, including those rich in chlorides and acids, meeting international standards like ASTM A995 and NACE MR0175.
