VT machining provides CNC Press Brake Forming 309S Stainless Steel for customers who need accurate, repeatable 309S Stainless Steel components. The machinability of 309S Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, so we set the operation up specifically for this grade.
CNC Press Brake Forming Capability for 309S Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 309S Stainless Steel with CNC Press Brake Forming
309S Stainless Steel behaves predictably under CNC Press Brake Forming 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 309S Stainless Steel run consistently from one batch to the next.
CNC Press Brake Forming Tolerances & Surface Finish
Formed 309S Stainless Steel holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
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 Press Brake Forming 309S Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed 309S Stainless Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Finished 309S 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.
CNC Press Brake Forming 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 309S Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Why 309S Stainless Steel?
309S 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 Press Brake Forming 309S Stainless Steel
Customers order CNC Press Brake Forming 309S 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.
