X6Cr17 is the same material your supplier may list as AISI 430 or JIS SUS430. This page maps the designations across standards and gives the ISO M-group machining starting point, brand-neutral.
| System | Designation |
|---|---|
| EN (EU) | X6Cr17 |
| Werkstoffnummer | 1.4016 |
| AISI / ASTM / UNS (US) | AISI 430 (UNS S43000) |
| JIS (Japan) | SUS430 |
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.
Ferritic, so no austenitic work-hardening drama: cuts closer to mild steel with a stainless smear tendency. Sharp edges and decent speed keep built-up edge away.
| ISO group | Starting Vc (coated carbide, turning) | Feed fn |
|---|---|---|
| M M · Stainless steel | 120–220 m/min · 395–720 sfm | 0.15–0.4 mm/rev · .006–.016 ipr |

X6Cr17 (Werkstoffnummer 1.4016) corresponds to AISI 430 (UNS S43000). In JIS terms the counterpart is SUS430.
It is an ISO M-group material, so the starting window is 120–220 m/min · 395–720 sfm at 0.15–0.4 mm/rev · .006–.016 ipr for coated-carbide turning, adjusted for condition and operation. For a grounded, brand-neutral pick — grade, geometry and cutting data across 15 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.
