Rust. Bare steel flash-rusts within hours in a humid container, so parts are oiled or passivated before packing unless you specify otherwise.
Machining S275JR Steel with CNC Waterjet Cutting
The machinability of S275JR Steel is good to excellent depending on carbon content; free-machining grades cut cleanly. For CNC Waterjet Cutting we select tooling, feeds, speeds and coolant to match, keeping the S275JR Steel workpiece stable and the result accurate.
Because we machine S275JR Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Waterjet Cutting S275JR Steel
| Feature | Standard | Precision |
|---|---|---|
| Contour dimension | ±0.10 mm | ±0.05 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Kerf width | 0.20 mm | 0.10 mm |
| Squareness of cut edge | 0.5° | 0.2° |
| Heat-affected zone | 0.15 mm | 0.05 mm (N₂ assist) |
| Minimum hole diameter | 1.2 × thickness | 1.0 × thickness |
| Edge condition | light dross | burr-free, N₂ cut |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Why S275JR Steel?
Specifying S275JR Steel for CNC Waterjet Cutting S275JR Steel is usually about its properties: strong, economical and widely available. Tell us the condition you need and we machine to it.
Design Tips for CNC Waterjet Cutting S275JR Steel
A few design choices make a real difference to cost and quality. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on S275JR Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
We complete S275JR Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
CNC Waterjet Cutting Tolerances & Surface Finish
Laser-cut S275JR Steel holds contour tolerances around ±0.05 mm depending on thickness, with a narrow kerf and a clean, near burr-free edge.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
CNC Waterjet Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on S275JR Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Applications of CNC Waterjet Cutting S275JR Steel
CNC Waterjet Cutting of S275JR Steel supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

What We Need to Quote CNC Waterjet Cutting S275JR Steel
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact S275JR Steel grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.
