| Grades we run | YG6, YG8, YG15 (K10–K30), D2, H13, M2, SKD11 |
Published typical values for WC-Co (YG8 / K20). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Everything is done by grinding, wire EDM or sinker EDM. Design in a small corner radius wherever possible — a true sharp internal corner doubles the EDM time.
Machining H13 Tool Steel with CNC Bending
When forming H13 Tool Steel, machinability is machined in the annealed state, then hardened; carbide tooling preferred. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for H13 Tool Steel mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Bending H13 Tool Steel
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 mm |
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.
Secondary Operations & Finishing
Most H13 Tool Steel parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Design Tips for CNC Bending H13 Tool Steel
Small design adjustments often cut cost and lead time. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed H13 Tool Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Bending Tolerances & Surface Finish
Formed H13 Tool Steel holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Why H13 Tool Steel?
Customers select H13 Tool Steel for CNC Bending because it is wear-resistant and hardenable for tooling. We handle grade verification and any required heat treatment or finishing.
CNC Bending Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Applications of CNC Bending H13 Tool Steel
H13 Tool Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC Bending H13 Tool 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 H13 Tool 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.
