Our Duplex Steel S31803 Tube Fittings has better localized corrosion resistance than Type 316L and Type 317L, and the steel is applied in the industrial fields such as chemical plant, seawater desalination plant, seawater pump, and so on. Meanwhile, these Duplex Steel S32205 Tube Fittings are as well being offered in different sizes and shapes to our customers. These Duplex Steel S31803 Union Fittings is readily weldable using many of the standard electric arc welding processes but oxyacetylene welding is not recommended because carbon pickup in the weld metal may occur.
The advantage of our Duplex Steel S32205 Union Fittings is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance). Sachiya Steel International is one of the prominent trader and dealer of these Duplex Steel S31803 Ferrule Fittings, which is suitable for cold forming.
