FAQ

Frequently Asked Questions

Find quick answers about stainless steel CNC machining, material grades, finishes, and production requirements.

We commonly machine 304, 316, 303, 17-4 PH, and 416 stainless steel, with other grades available based on project requirements.

304 is generally easier and more cost-effective to machine, while 316 offers higher corrosion resistance for marine, chemical, and harsh environments.

Yes. Stainless steel parts can be passivated after machining to remove free iron from the surface and improve corrosion resistance.

Typical CNC machining tolerances are ±0.01 mm, with tighter tolerances down to ±0.005 mm available for selected critical features depending on part geometry, size, material grade, and inspection requirements.

Yes. Material certificates can be provided upon request. Please specify any certification or traceability requirements when requesting a quote.

Available finishes include passivation, bead blasting, polishing, and as-machined finishes depending on your requirements.
