The Duplex Steel S31803 pipes produced by Victor Nickel Alloys in Abuja, Nigeria, contain about 22% chromium, 5–6% nickel, and 3% molybdenum, which gives them outstanding resistance to corrosion and pitting. Thanks to their balanced duplex microstructure, these pipes boast superior strength and toughness compared to regular austenitic steels. They feature impressive tensile strength (around 620 MPa), yield strength (450 MPa), and excellent elongation and hardness. Their low thermal expansion and high thermal conductivity make them ideal for challenging conditions, ensuring they remain durable, resist stress corrosion cracking, and perform reliably under high pressure.
