CNC Sinker EDM 302 Stainless Steel is part of VT machining's grade-specific capability. 302 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 Sinker EDM Capability for 302 Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 302 Stainless Steel with CNC Sinker EDM
302 Stainless Steel behaves predictably under CNC Sinker EDM once parameters are dialled in: machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of 302 Stainless Steel run consistently from one batch to the next.
CNC Sinker EDM Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every 302 Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 302 Stainless Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Design Tips for CNC Sinker EDM 302 Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened 302 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.
Secondary Operations & Finishing
Finished 302 Stainless Steel parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Why 302 Stainless Steel?
302 Stainless Steel is chosen when a part needs what this grade offers — it is corrosion resistant, strong and hygienic. We confirm the grade and any temper or heat-treat condition with you before machining.
Applications of CNC Sinker EDM 302 Stainless Steel
Customers order CNC Sinker EDM 302 Stainless Steel components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.
