The plate exhibits excellent resistance to pitting and crevice corrosion in harsh environments with chlorides or other contaminants. When heated between 1,500°F and 1,900°F, the Duplex plate forms an adherent, self-healing chromium oxide layer only a few nanometers thick. This chromium enrichment phenomenon further enhances corrosion performance while also providing good resistance to oxidation and scale buildup. So the material retains its surface qualities in high-temperature applications like heat exchangers and refinery process piping.

The plate metal is well suited to welding and other forms of material joining using standard duplex practices. Precautions include controlling heat input to avoid precipitation of intermetallic compounds.

Post-weld treatments such as pickling should be applied to remove oxides and fully restore corrosion resistance. Machining the plate for fabrication also requires correct techniques and tooling but can be performed with good productivity at optimal conditions.

Due to its high mechanical strength, weldability, appreciable ductility, outstanding corrosion performance, and overall ease of fabrication, the UNS S31803 Foil Sheet offers versatility across many process industries.

It provides durable service for pipes, tanks, pressure vessels, offshore platforms, pumps and valves, and any components exposed to oxidizing acids, chlorine bearing environments, or high temperatures. With proper joining techniques and handling precautions applied, the properties of 31803 can be fully utilized to improve critical infrastructure integrity and lifecycle costs.
