New Fashion Design for Iron Casting Foundry - Custom Stainless Steel Impeller by Investment Casting – RMC Foundry Detail:

China OEM custom stainless steel impeller by lost wax investment casting process.

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.

Stainless steel has a minimum chromium content of 10.5%, making it more resistant to corrosive liquid environments and to oxidation. However, this is not absolute. 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.

Advantages of Investment Casting Components:
- Excellent and smooth surface finish
- Tight dimensional tolerances.
- Complex and intricate shapes with design flexibility
- Capability to cast thin walls therefore a lighter casting component
- Wide selection of cast metals and alloys (ferrous and non-ferrous)
- Draft is not required in the molds design.
- Reduce the need for secondary machining.
- Low material waste.
