Fajar Metals’ Duplex Steel Sheets and Plates are generally crafted from grades like UNS S31803 or S32205. Their makeup consists of around 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, all balanced with iron. These dual-phase (austenitic-ferritic) alloys deliver outstanding corrosion resistance, especially against stress corrosion cracking and pitting. The mechanical properties include impressive tensile strength (620–800 MPa), yield strength (~450 MPa), and elongation of 25–30%. This material remains stable under high pressure and temperature, making it perfect for structurally demanding and corrosive environments. All products comply with ASTM A240 and equivalent international standards.
