VT machining provides CNC Waterjet Cutting 4340 Alloy Steel for customers who need accurate, repeatable 4340 Alloy Steel components. The machinability of 4340 Alloy Steel is good in annealed condition; machined soft then heat-treated to final hardness, so we set the operation up specifically for this grade.
CNC Waterjet Cutting Capability for 4340 Alloy Steel
- Cr-Mo / Ni-Cr-Mo grades
- High strength & hardenability
- Tolerance to ±0.01 mm
- Heat-treatable to 30–55 HRC
Machining 4340 Alloy Steel with CNC Waterjet Cutting
The machinability of 4340 Alloy Steel is good in annealed condition; machined soft then heat-treated to final hardness. For CNC Waterjet Cutting we select tooling, feeds, speeds and coolant to match, keeping the 4340 Alloy Steel workpiece stable and the result accurate.
Because we machine 4340 Alloy Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Why 4340 Alloy Steel?
Specifying 4340 Alloy Steel for CNC Waterjet Cutting 4340 Alloy Steel is usually about its properties: high-strength and hardenable. Tell us the condition you need and we machine to it.
CNC Waterjet Cutting Tolerances & Surface Finish
Laser-cut 4340 Alloy 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.
Secondary Operations & Finishing
We complete 4340 Alloy 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.
Design Tips for CNC Waterjet Cutting 4340 Alloy 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 4340 Alloy Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Waterjet Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 4340 Alloy 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.
