Procurement FAQ

Which stainless grades are common?

Common grades include 304, 316L, 17-4PH, and other drawing-specified stainless steels.

Is stainless harder to machine than aluminum?

Yes. Stainless steel usually needs slower cutting, stable tooling, and careful burr control.

What tolerance target applies?

The site-wide tolerance target is ±0.002mm, subject to geometry and material condition.

Can passivation be arranged?

Passivation and other finishing steps can be coordinated when required.
