CNC Sinker EDM 431 Stainless Steel from VT machining delivers precision 431 Stainless Steel parts made to your exact drawing. Sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features, with parameters tuned to 431 Stainless Steel, which is corrosion resistant, strong and hygienic.
CNC Sinker EDM Capability for 431 Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 431 Stainless Steel with CNC Sinker EDM
The machinability of 431 Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. For CNC Sinker EDM we select tooling, feeds, speeds and coolant to match, keeping the 431 Stainless Steel workpiece stable and the result accurate.
Because we machine 431 Stainless Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
CNC Sinker EDM Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 431 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.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 431 Stainless Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
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.
Secondary Operations & Finishing
We complete 431 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.
Design Tips for CNC Sinker EDM 431 Stainless Steel
A few design choices make a real difference to cost and quality. EDM suits sharp internal corners, thin ribs and hardened 431 Stainless Steel that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.

Request a QuoteFrequently Asked Questions
Can you EDM-machine hardened 431 Stainless Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 431 Stainless Steel can be machined to fine detail and tight tolerance without distortion.
What surface finish is achievable on 431 Stainless Steel with CNC Sinker EDM?
Surface finish on 431 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Sinker EDM 431 Stainless Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Can VT machining make custom 431 Stainless Steel parts to my drawing?
Yes. 431 Stainless Steel 431 Stainless Steel EDM machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
