| Yield strength (0.2%) | — |
| Hardness | 88–93 HRA / 1300–1800 HV |
| Melting point | 2870 (WC) °C |
| Thermal conductivity | 70–100 W/m·K |
| Thermal expansion | 5.0 ×10⁻⁶/K |
| Electrical conductivity | 10% |
| Machinability (C36000 = 100%) | grind / EDM only |
| 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 Gear Cutting
H13 Tool Steel behaves predictably under CNC Gear Cutting once parameters are dialled in: machinability is machined in the annealed state, then hardened; carbide tooling preferred, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of H13 Tool Steel run consistently from one batch to the next.
Achievable Tolerances for CNC Gear Cutting H13 Tool Steel
| Feature | Standard | Precision |
|---|---|---|
| Accuracy class | DIN 8 / AGMA 10 | DIN 6 / AGMA 12 |
| Profile deviation | 0.020 mm | 0.008 mm |
| Lead deviation | 0.020 mm | 0.008 mm |
| Pitch deviation (cumulative) | 0.040 mm | 0.015 mm |
| Runout | 0.030 mm | 0.010 mm |
| Tooth surface finish | Ra 1.6 µm | Ra 0.4 µm (ground) |
| Module range | m0.5–m8 | m1–m6 |
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.
Design Tips for CNC Gear Cutting H13 Tool Steel
We are happy to suggest design tweaks that improve manufacturability. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce H13 Tool Steel gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Finished H13 Tool 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 H13 Tool Steel?
H13 Tool Steel is chosen when a part needs what this grade offers — it is wear-resistant and hardenable for tooling. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Gear Cutting Tolerances & Surface Finish
Gear features are produced to a specified DIN/AGMA accuracy class, with profile and lead controlled for quiet, durable running under load.
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.
CNC Gear Cutting 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 H13 Tool Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Applications of CNC Gear Cutting H13 Tool Steel
Customers order CNC Gear Cutting H13 Tool 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 Gear Cutting H13 Tool 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.
Finishing Options for H13 Tool Steel
| Finish | Thickness / effect | Why it gets specified |

| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Gear Cutting 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.
