Santner Nickel Alloys, headquartered in Hamilton, New Zealand, is a leading manufacturer and supplier of Duplex Steel S31803 forged fittings. Known for their exceptional combination of strength, corrosion resistance, and durability, these fittings are precision-forged to meet stringent industry standards. The S31803 duplex steel microstructure offers superior performance in challenging environments, including chemical, petrochemical, and offshore applications. With excellent resistance to stress-corrosion cracking and pitting, these fittings provide long-lasting reliability under high pressure and fluctuating temperatures. Engineers and fabricators trust Santner Nickel Alloys’ Duplex Steel S31803 forged fittings for robust, safe, and efficient piping and structural solutions.
Duplex Steel S31803 forged fittings are composed of a balanced combination of iron, chromium, nickel, and molybdenum, with small amounts of nitrogen and manganese. This dual-phase austenitic-ferritic microstructure delivers high tensile and yield strength, superior toughness, and excellent fatigue resistance. The alloy exhibits outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking, particularly in chloride-containing environments. S31803 fittings maintain dimensional stability under high pressures and thermal cycling. Their excellent weldability, ductility, and mechanical performance make them ideal for industrial applications requiring durable and reliable duplex steel components.
