Frequently Asked Questions

How much does it cost to cast stainless steel?

Per-unit costs depend heavily on the specific alloy grade, part complexity, production volume, and required secondary machining. Standard grades like 304 cost less to source and pour than specialized options like 17-4 PH.

High-volume production runs spread the initial tooling investment across the entire production run, so the cost per part decreases at scale. We evaluate your exact geometric and material requirements to provide an accurate production quote.

Is investment casting cheaper than die casting?

Die casting often offers lower per-unit costs at extremely high volumes, but it is restricted to lower-melting-point alloys like aluminum or zinc. Investment casting is required for high-melting-point metals like stainless steel. This process also typically carries lower initial tooling costs than die casting, making it highly cost-effective for complex geometries that demand superior corrosion resistance and strength.

Is casting weaker than forging?

Forging aligns the internal grain structure of the metal to provide maximum directional strength. Stainless steel investment casting provides excellent multi-directional durability and allows for highly complex geometries that simply can’t be forged. The casting process delivers near-net shapes that reduce machining time while maintaining the required mechanical properties for demanding industrial applications.
