Stainless steel has a minimum chromium content of 10.5%, making it more resistant to corrosive liquid environments and to oxidation. It is highly corrosion resistant and wear resistant, provides excellent machinability, and is well-known for its aesthetic appearance. Stainless steel investment castings are "corrosion-resistant" when used in liquid environments and vapors below 1200°F (650°C) and "heat-resistant" when used above this temperature.

Heat Treatment of AISI 316 Stainless Steel Castings:
Heat to 1900°F (1040°C) minimum, holding for sufficient time, quench in water or rapid cool by other means. AISI 316 equal to CF8M/F316 and Chinese Standard 0Cr17Ni12Mo2. AISI 314 is a molybdenum bearing modification of AISI 304 alloy and is the cast equivalent of wrought CF8M Stainless steel. The presence of molybdenum increases the general corrosion resistance and the resistance to pitting by chlorides. The alloy is used in mildly acidic and alkaline conditions and for handling citric, oxalic and phosphoric acids.
