Identify the stainless designation precisely
304 and 304L are distinct material designations. Specify the grade and condition required by the approved drawing; do not assume one is a universal substitute for the other. This page covers machining a part, while grade information belongs to the materials section.
See 304/304L material details and the stainless steel overview. For machining scope, see CNC turning or CNC milling.
Define the functional dimensions
- Mark datums, fits, holes, bores and threaded features.
- State material grade, condition, quantity and drawing revision.
- Specify surface finish and any post-machining treatment.
- List critical inspection dimensions and required records.
A material designation does not define the finished-part tolerance or service performance. Set acceptance requirements on the drawing and identify the stage at which dimensions are measured.

Send the current CAD and drawing, quantity, finish and inspection scope. If the application has special environmental requirements, state them for review rather than assuming the grade alone resolves them.
