Custom Stainless Steel Castings

Stainless steel castings are the castings made of stainless steel. Usually, most of the stainless steel castings are made by lost wax casting process due to that the better surface and higher accuracy. However, at RMC casting foundry, for some large-scaled castings, we also cast and pour the stainless steel by sand casting, shell mold casting and other casting processes.

Due to its unique physical properties, stainless steel castings are popular in a wide range of applications, especially those in harsh environments. Common markets for stainless steel investment castings include oil and gas, fluid power, transportation, hydraulic systems, food industry, hardware and locks, agriculture...etc.

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.

The base alloy elements of any nickel-base or stainless steel investment casting are chromium, nickel, and molybdenum (or "moly"). These three components will determine the casting's grain structure and mechanical properties and will be instrumental in the casting's ability to combat heat, wear, and corrosion.
