Starting cutting speed in m/min and sfm, feed in mm/rev and ipr, the carbide grade class and the setup by operation for AISI 316 (X5CrNiMo17-12-2). The numbers are the published M01 Austenitic (304, 316L) sub-group starting band; the designations are on the cross-reference page.

Hardness is the range published for the whole M01 Austenitic (304, 316L) sub-group on our material guide; the delivery condition of your AISI 316 may sit anywhere inside it or outside it.
| Condition | Vc m/min | Vc sfm | Feed mm/rev | Feed ipr |
|---|---|---|---|---|
| M01 Austenitic (304, 316L), 150–220 HB | 120–200 | 395–655 | 0.10–0.35 | .004–.014 |
Sub-group starting values for carbide inserts, from M01 Austenitic (304, 316L). They describe the whole sub-group and are not tuned to AISI 316. sfm and ipr are converted from the metric values (1 m/min = 3.281 sfm, 25.4 mm = 1 in). The published band is per sub-group, not per operation; the table below gives the setup by operation. Convert Vc to spindle speed with the speeds & feeds calculator, and see the speeds & feeds guide for the ISO M group range.
| Operation | Geometry | Coating family | Coolant | First check |
|---|---|---|---|---|
| Roughing | Positive rake, lightly honed edge, open polished chipbreaker; avoid a heavy negative land | Tough PVD-coated carbide | High-pressure coolant 15–20 bar aimed at the edge | Consistent depth of cut: stay above the work-hardened layer |
| Finishing | Positive rake, sharp edge, polished chipbreaker | PVD-coated carbide, sharper edge | High-pressure coolant 15–20 bar | Built-up edge: Vc too low or tool dwelling |
| Interrupted cut | Positive but robust honed edge | Tougher PVD-coated carbide | High-pressure coolant 15–20 bar | Notch wear at the depth-of-cut line: vary DOC between passes |
| Low rigidity / thin wall | Positive rake, sharp edge to avoid pushing the material | PVD-coated carbide | High-pressure coolant 15–20 bar | Feed high enough for the chipbreaker to engage |
Setup rows are the selection table of the M01 Austenitic (304, 316L) guide. They carry no speeds, so they do not change the starting band above.
Same sub-group, same starting band: AISI 303 · AISI 304 · AISI 304L · AISI 316L · AISI 316Ti · AISI 321
Tough PVD-coated carbide. Roughing ≈ M25–M30 for heat and edge security; finishing ≈ M10–M20 for a sharper edge and better surface.
The P, M, K, N, S or H number inside a grade range describes what the grade is built for, not the workpiece sub-group number, and the two scales must not be matched to each other. We name no single grade here: none of our published sources ties a named grade to this alloy. Pick by ISO class, then compare what the makers publish on the ISO M grade list and in the grade chart.
EN X5CrNiMo17-12-2, Werkstoffnummer 1.4401, US AISI 316 (UNS S31600), JIS SUS316. The full table, with the nearest-match flags, is on the AISI 316 / 1.4401 cross-reference page.
Molybdenum adds corrosion resistance and a little extra toughness in the cut versus 304. Same M-group rules: positive sharp geometry, constant feed, generous coolant.

The published starting band for the M01 Austenitic (304, 316L) sub-group is 120–200 m/min (395–655 sfm) at 0.10–0.35 mm/rev (.004–.014 ipr). It is a starting band for the whole sub-group, not a value tuned to AISI 316, so confirm on a sample part and adjust for condition, tool and rigidity.
Tough PVD-coated carbide. Roughing ≈ M25–M30 for heat and edge security; finishing ≈ M10–M20 for a sharper edge and better surface. Pick the grade by ISO class rather than by brand name, then confirm the exact grade for your condition. We name no single grade here because none of our published sources ties a named grade to this alloy.
