Paulo Products Company has added two surface treatments at its St. Louis, Mo., facility. Paulo-St. Louis now has the capability to perform gas nitriding. In addition, Paulo-St. Louis has added the capability to perform a corrosion-resistant ferritic nitrocarburizing process on carbon and alloy steels.
The gas nitriding is carried out in a sealed retort with an ammonia atmosphere at temperatures at or near 1000°F. Typical cycle times range from 24-72 hours. Paulo-St. Louis can accommodate parts up to 48 inches in length. The corrosion-resistant ferritic nitrocarburizing process incorporates an oxidizing stage that enhances corrosion resistance as well as improves appearance and overall performance.
