Fajar Metals is well-regarded for its engineering know-how, quick turnaround times, and robust products that deliver exceptional strength and resistance to corrosion.
Duplex Steel Forgings, typically made from UNS S31803 or S32205 grades, feature around 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, all balanced with iron. This dual-phase (ferritic-austenitic) structure offers a perfect blend of strength and corrosion resistance. These forgings boast a tensile strength ranging from 620 to 880 MPa, a yield strength of about 450 MPa, and impressive elongation (≥25%). Their ability to resist chloride-induced stress corrosion cracking, pitting, and crevice corrosion makes them ideal for harsh and mechanically demanding environments. They maintain their mechanical integrity even under high pressure, elevated temperatures, and cyclic loading.
