VT machining specialises in CNC Milling 904L Stainless Steel. Because 904L Stainless Steel is corrosion resistant, strong and hygienic, and its machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, we plan each job around the grade to protect accuracy and surface quality.
CNC Milling Capability for 904L Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 904L Stainless Steel with CNC Milling
The machinability of 904L Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. For CNC Milling we select tooling, feeds, speeds and coolant to match, keeping the 904L Stainless Steel workpiece stable and the result accurate.
Because we machine 904L Stainless Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Secondary Operations & Finishing
We complete 904L Stainless Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Why 904L Stainless Steel?
Specifying 904L Stainless Steel for CNC Milling 904L Stainless Steel is usually about its properties: corrosion resistant, strong and hygienic. Tell us the condition you need and we machine to it.
CNC Milling Tolerances & Surface Finish
For CNC Milling, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
CNC Milling Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 904L Stainless Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Design Tips for CNC Milling 904L Stainless Steel
A few design choices make a real difference to cost and quality. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in 904L Stainless Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Milling 904L Stainless Steel
CNC Milling of 904L Stainless Steel supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.
