Being intended to maintain high durability and withstand the pressure of steam, these WNR 1.4462 Duplex Steel S31803 Pipe Unions are resistant to stress corrosion cracking from sulfur. Duplex Steel S31803/S32205 Seamless Pipe Fittings from the inventory at Oshwin are workable and weldable. They display high ductility, even at signified low temperatures.
Our UNS S31803 duplex steel pipes and tubes are used in industrial applications precisely because of the tensile strength and hardness of the material. While the UNS S32205 duplex steel pipes and tubes provide much corrosion resistance, they have a lower grade of resistance to stainless steel. These pipes and tubes are extensively applied in the chemical processing, oil and gas, marine, food, and pollution control industries.
We offer high-quality Duplex Steel Seamless Pipes in various sizes and shapes nationwide and overseas. We offer our Super Duplex Steel Seamless Tubes in multiple dimensions and shapes, with competitive pricing, to meet quality rigorously.
