Typical Stainless Steel Parts
Shafts, sleeves, connectors, fixtures, industrial brackets, and precision structural parts.
Custom Stainless Steel Machined Parts
Stainless steel combines corrosion resistance, strength, and durability, but work hardening, heat generation, tool wear, burr control, and distortion must be considered during process planning.
CNC Milling and Turning
CNC milling supports housings, plates, brackets, and fixtures, while CNC turning supports shafts, sleeves, bushings, pins, and round connectors.
Inspection-Controlled Production
Inspection can be planned around datums, fits, threads, bores, sealing features, surface finish, and other dimensions identified as critical on the drawing.
Stainless Steel Grades and Selection
The final grade must be specified or approved during drawing review. Availability, certification, heat treatment, magnetic response, welding, corrosion exposure, and finish requirements can affect the choice.
| Grade family | Typical reason for selection | Machining consideration |
|---|---|---|
| 304 stainless steel | General corrosion resistance and broad industrial use | Tooling, feeds, coolant, and burr control are planned to manage work hardening |
| 316 stainless steel | Improved corrosion resistance for demanding environments | Material condition and critical surfaces should be defined on the RFQ |
| 17-4 PH stainless steel | Strength and corrosion resistance where precipitation-hardening grades are appropriate | Heat-treatment condition can affect machining sequence and final dimensions |
| Other specified grades | Application-specific mechanical, corrosion, or regulatory requirements | Confirm the exact standard, grade, condition, certificate, and acceptable substitutions |
Information Needed for a Stainless Steel CNC Quote
CAD and Drawings
Send a STEP or STP model with a dimensioned PDF drawing that identifies datums, tolerances, threads, surface finish, and inspection requirements.
Material and Finish
State the stainless steel grade, condition, certificate or traceability needs, passivation or other finish, masking, cosmetic areas, and acceptance criteria.
Quantity and Delivery
Include prototype and production quantities, packaging needs, destination, and target delivery date so the manufacturing scope can be reviewed together.
Stainless Steel Machining FAQ
Which stainless steel grades can be machined?
Projects using 304, 316, 17-4 PH, and other specified grades can be reviewed. The approved grade, material condition, certificate requirements, and substitutions are confirmed before production.
Can you make stainless steel shafts and sleeves?
Yes. CNC turning can support shafts, sleeves, pins, bushings, connectors, and other rotational parts, subject to diameter, length, tolerance, surface finish, and quantity review.
What tolerances are available?
Achievable tolerances depend on geometry, size, material condition, datums, workholding, finishing, and inspection method. Send the drawing so critical dimensions can be reviewed instead of relying on a blanket tolerance claim.
