C60 is the same material your supplier may list as AISI 1060 or JIS S58C. This page maps the designations across standards and gives the ISO P-group machining starting point, brand-neutral.
| System | Designation |
|---|---|
| EN (EU) | C60 |
| Werkstoffnummer | 1.0601 |
| AISI / ASTM / UNS (US) | AISI 1060 (UNS G10600) |
| JIS (Japan) | S58C (nearest) |
Compiled from the public standard designation systems (EN 10027, SAE/AISI, ASTM, UNS, JIS). Entries marked “nearest” are the closest commonly-cited counterpart, not a drop-in equivalent. Always verify against the material certificate.
Higher carbon means higher strength and more flank-wear pressure than C45; drop Vc toward the lower half of the P range and keep feeds moderate.
| ISO group | Starting Vc (coated carbide, turning) | Feed fn |
|---|---|---|
| P P · Steel | 150–350 m/min · 490–1150 sfm | 0.1–0.5 mm/rev · .004–.020 ipr |

C60 (Werkstoffnummer 1.0601) corresponds to AISI 1060 (UNS G10600). In JIS terms the counterpart is S58C (nearest).
It is an ISO P-group material, so the starting window is 150–350 m/min · 490–1150 sfm at 0.1–0.5 mm/rev · .004–.020 ipr for coated-carbide turning, adjusted for condition and operation. For a grounded, brand-neutral pick — grade, geometry and cutting data across 13 brands — ask the advisor.
They designate the same composition under different systems, but the drawing standard governs: certificates, tolerances and delivery-condition requirements differ between standards even for equivalent chemistry. Substitute only with the certificate in hand.
Knowing the material is half the job; picking the grade and cutting data for the operation is the other half. That is what the advisor does, grounded in catalog data and honest when there is no verified match.
