317 pipe spools superior chloride pitting and general corrosion resistance
One exception, however, are strongly oxidizing acids such as nitric acid. Alloys that contain molybdenum generally do not perform as well in these environments.?
The low carbon content of Alloy 317L allows it to be welded without intergranular corrosion due to chromium carbide precipitation, allowing it to be used in the as-welded condition. The alloy is dual certified to Alloy 317 (UNS S31700) with the addition of nitrogen as a strengthening agent. Some other applications for Gold 317L include
Paper and pulp processing equipment, chemical and petrochemical processing equipment, and condensers for fossil fuel and nuclear fuel power plants.
