A development regarding carbon additions in nitrogen-alloyed stainless steels presents intriguing possibilities for the future of chromium-manganese based stainless steels. With proper levels of carbon and nitrogen, a cast material can be made that will not form carbides or nitrides, alleviating concern over localized corrosion. The metallurgical requirements to achieve enhanced properties will be considered.
Work has been done to economically produce austenitic stainless steel alloys with improved mechanical properties and corrosion resistance. The combination of a series of casting practices is crucial in manufacturing high-carbon nitrogen-alloyed austenitic stainless steel castings with minimal inclusions. The practices to economically produce these castings at atmospheric pressure will be discussed.
Alloys of moderate to high nitrogen and carbon concentrations have been produced and examined in comparison to commercially available stainless steels. A review of melting trials, microstructural features, and the results of mechanical testing and corrosion resistance assessment will be presented.
