FAQ

Q: Why use 304 stainless steel for an investment-cast impeller?

A: 304 stainless offers excellent corrosion resistance (especially in water, chemicals, and mild acids), good weldability, and moderate strength-ideal for pumps, mixers, and marine applications where rust prevention is critical.

Q: What's the minimum achievable wall thickness for a 304 impeller?

A: Investment casting allows walls as thin as 1.5–2 mm (0.06–0.08 in) for 304 stainless steel, though thicker sections (3+ mm) improve structural integrity in high-speed or high-pressure systems.

Q: Can you match existing impeller designs or reverse-engineer samples?

A: Yes. Provide a drawing, sample part, or 3D scan, and we'll replicate geometries, including complex blade profiles, with typical tolerances of ±0.5 mm (±0.020 in) for as-cast parts.
