VT machining specialises in CNC Honing 440C Stainless Steel. Because 440C 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 Honing Capability for 440C Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 440C Stainless Steel with CNC Honing
440C Stainless Steel behaves predictably under CNC Honing 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 440C Stainless Steel run consistently from one batch to the next.
CNC Honing Tolerances & Surface Finish
Finishing brings 440C Stainless Steel to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
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.
Why 440C Stainless Steel?
440C 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.
CNC Honing 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 440C Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Secondary Operations & Finishing
Finished 440C 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.
Design Tips for CNC Honing 440C Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish 440C Stainless Steel efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
