What drives the real part cost

Material price is only one input. The full per-part cost adds machine time at your all-in hourly rate, hands-on labor, a failure or scrap allowance, and your margin. On most Stainless 304/316 parts, machine time and labor outweigh the material itself — which is why per-kg price comparisons alone mislead.

Pro tip

Quote stainless at roughly 1.5-2x your mild steel machining time for the same geometry.
