This article reviews the properties of cast steels that are specified for liquid corrosion service at temperatures above and below 650 deg C. Stainless steel castings are usually classified based on their resistance to corrosion and heat and generally fall into one category or the other. The article describes alternate methods for classifying cast stainless steels, one is based on grade designations, the other on microstructural analysis. It also addresses heat treatment, pointing out its similarities with the thermal processing of wrought materials, and establishes the importance of mechanical properties in material selection. The article presents information on the...
