CNC Tapping S355JR Steel

VT machining specialises in CNC Tapping S355JR Steel. Because S355JR Steel is strong, economical and widely available, and its machinability is good to excellent depending on carbon content; free-machining grades cut cleanly, we plan each job around the grade to protect accuracy and surface quality.

CNC Tapping Capability for S355JR Steel

• Carbon/low-alloy grades
• Economical & weldable
• Tolerance to ±0.02 mm
• Hardenable by heat treat

Machining S355JR Steel with CNC Tapping

S355JR Steel behaves predictably under CNC Tapping once parameters are dialled in: machinability is good to excellent depending on carbon content; free-machining grades cut cleanly, and we tune the operation accordingly.

We hold reference parameters for this grade, so repeat orders of S355JR Steel run consistently from one batch to the next.

CNC Tapping 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 S355JR Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.

Secondary Operations & Finishing

Finished S355JR 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 S355JR Steel?

S355JR Steel is chosen when a part needs what this grade offers — it is strong, economical and widely available. We confirm the grade and any temper or heat-treat condition with you before machining.

Design Tips for CNC Tapping S355JR Steel

We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in S355JR Steel. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC Tapping Tolerances & Surface Finish

For CNC Tapping, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.

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.

Applications of CNC Tapping S355JR Steel

Customers order CNC Tapping S355JR 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.

How to Order CNC Tapping S355JR Steel

Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
