CNC EDM Drilling 431 Stainless Steel is part of VT machining's grade-specific capability. 431 Stainless Steel is corrosion resistant, strong and hygienic, and we combine controlled EDM machining with material-aware setup to produce parts that meet your specification.
CNC EDM Drilling 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 EDM Drilling
When EDM machining 431 Stainless Steel, machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for 431 Stainless Steel mean predictable cycle times and stable, repeatable results.
CNC EDM Drilling 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.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Secondary Operations & Finishing
Most 431 Stainless Steel parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
CNC EDM Drilling Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Design Tips for CNC EDM Drilling 431 Stainless Steel
Small design adjustments often cut cost and lead time. 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.
Why 431 Stainless Steel?
Customers select 431 Stainless Steel for CNC EDM Drilling because it is corrosion resistant, strong and hygienic. We handle grade verification and any required heat treatment or finishing.

Which industries use CNC EDM Drilling 431 Stainless Steel parts?
CNC EDM Drilling 431 Stainless Steel parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise 431 Stainless Steel components are required.
What is CNC EDM Drilling 431 Stainless Steel and how is it done?
CNC EDM Drilling 431 Stainless Steel refers to fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM. Applied to 431 Stainless Steel — corrosion resistant, strong and hygienic — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
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.
How clean are the edges produced by CNC EDM Drilling on 431 Stainless Steel?
Machined 431 Stainless Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
