MACHINABILITY OF 301 STAINLESS STEEL
Stainless steel 301 is an austenitic stainless-steel alloy with 17% chromium and 7% nickel.
It is a simple chromium-nickel stainless with 0.1% carbon that exhibits excellent resistance to atmospheric corrosion but is not suitable for harsh environments. It is relatively easy to machine (compared with other austenitic alloys) with a machinability rating of 52%.
SUMMARY:
For general Turning of Stainless Steel 301 at stable conditions use a grade with a Semi Hard substrate and Thin CVD coating.
In case you are running at a cutting speed that is lower than 390 SFM (120 m/min), it is better to use a grade with a Semi Hard substrate and PVD coating.
For general Milling use a grade with a Semi Hard substrate and Thin PVD coating.
For detailed carbide grades recommendations,check the table below.
Recommended cutting speed range for turning at stable conditions is 640 - 850 [SFM] / 195 - 260 [m/min].
Recommended cutting speed range for milling with stable clamping and short over hang is 390 - 540 [SFM] / 120 - 165 [m/min].
For detailed cutting speed recomendations, check the table below.

Important! The speed estimation is given for an ideal situation:
- Most suitable carbide grade
- Stable tool clamping
- Stable workpiece clamping
- Good quality raw material
- A short overhang of the cutting tool.
- Nominal hardness of the material.
- etc.
