Low MOQ for Aluminium Casting Foundry - Stainless Steel AISI 316 Investment Casting Pump Housing – RMC Foundry Detail:

OEM custom stainless steel castings produced by lost wax investment casting and CNC machining services. The AISI 316 / CF8M stainless steel are widely used to produce the stainless steel pump housing or end cover due to its good anti-rust performance.

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.

Our foundry can manufacture custom stainless steel investment castings that match your exact design specifications. For parts ranging from tens of grams to tens of kilograms or more, we provide tight tolerances and consistent part to part repeatability.

Commonly, the stainless steel should be cast by the investment precision casting process with the silica sol as the bond. The stainless steel silica sol castings have a very high grade of precision surface and performance.

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.
