The basic alloying elements for any nickel-based or stainless steel casting are chromium, nickel and molybdenum (or "molybdenum"). These three components will determine the grain structure and mechanical properties of the casting and will contribute to the ability of the casting to resist heat and/or corrosion.
Stainless steel has a minimum chromium content of 10.5%, making it more resistant to corrosive liquid environments and oxidation. However, this is not absolute. Stainless steel investment castings are "corrosion resistant" for service in liquid environments and steam below 1200°F (650°C) and "heat resistant" for service above this temperature.
There are differences between wrought and cast versions of stainless steel. This is due to their chemical composition and microcrystalline structure, which is affected by how the material is produced, cast or extruded. These factors must be considered when selecting an alloy for a stainless steel investment cast metal project.
