Duplex Tube Fittings mainly consist of iron (balance), chromium (19–22%), nickel (4–6%), and molybdenum (2–3%), with trace amounts of nitrogen added to boost strength and corrosion resistance. On the mechanical side, they showcase a tensile strength ranging from 700 to 900 MPa, along with excellent yield strength and impressive fatigue resistance. They maintain toughness, dimensional stability, and reliable mechanical performance across a broad temperature spectrum, including highly corrosive environments rich in chlorides and elevated temperatures, ensuring dependable operation in critical piping systems.
