Our Duplex Steel S31803 Tube Fittings are celebrated for their remarkable strength, durability, and impressive resistance to corrosion, even in harsh conditions. Crafted to meet international standards, these fittings guarantee reliable performance, a long lifespan, and precise dimensions. We cater to a variety of industries, including oil and gas, chemical, petrochemical, marine, and power generation, providing high-performance Duplex Steel S31803 Tube Fittings that meet their specific needs.
These fittings are made up of 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, which together create a well-balanced duplex microstructure. This composition gives them high tensile and yield strength, exceptional hardness, and strong resistance to pitting and crevice corrosion. Their mechanical properties also include excellent fatigue strength, impact toughness, and resistance to stress corrosion cracking. With outstanding weldability and dimensional stability, Duplex Steel S31803 Tube Fittings are perfect for high-pressure and corrosive service conditions.
