ISO 513 group P (Steel): workpiece materials, grades and selection
What ISO 513 group P covers
| Group | P — Steel (identification colour: blue) |
|---|---|
| Workpiece materials | Plain carbon steel, alloy steel, tool steel and cast steel. Long, continuous chips. |
| Application band | P01 (fine finishing) – P50 (heavy roughing) |
| Grade behaviour | Grades need hot hardness and crater-wear resistance at the high cutting speeds steel allows. Toughness is traded against wear resistance along the P01–P50 band. |
| Typical coating family | CVD multilayer (TiCN/Al2O3) grades dominate general steel turning; PVD grades cover finishing and interrupted cuts. |
| Selection guidance | For stable continuous cuts pick wear-resistant mid-band grades (P15–P35); for interrupted or slender setups step toward tougher grades (P35–P50). |
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.
