Steels are now used for a wide variety of conditions entailing heat and corrosion under both static and dynamic stresses such as aero engine valves, furnace conveyers, retorts, oil cracking units and gas turbines. Stainless steel castings are usually classified as either corrosion-resistant steel castings or heat-resistant steel casting. The usual distinction between heat-resistant and corrosion-resistant cast steels is based on carbon content
