ISO 513 group S (Heat-resistant superalloys & titanium): workpiece materials, grades and selection
What ISO 513 group S covers
| Group | S — Heat-resistant superalloys & titanium (identification colour: brown) |
|---|---|
| Workpiece materials | Heat-resistant superalloys (nickel/cobalt base, e.g. Inconel-type), titanium alloys. Hot, strong, abrasive. |
| Application band | S01 (finishing) – S30 (roughing) |
| Grade behaviour | Edge temperature control is decisive: grades need hot hardness plus toughness against notch wear and plastic deformation at moderate speeds. |
| Typical coating family | Thin PVD coatings with fine-grain substrates are typical; thick CVD multilayers can spall under these loads. |
| Selection guidance | Use strong edge preparations, moderate speeds and generous coolant strategy or high-pressure coolant where available. |
Group definition, identification colour and band numbering per ISO 513 (classification of carbides by use). Behaviour and coating notes are general engineering guidance, not manufacturer cutting data.
