Machining Stainless Steel 317

Stainless Steel 317 is an austenitic stainless steel alloy with 19% chromium and 13% nickel.

It is a chromium-nickel-molybdenum stainless with low carbon (0%) content. The low carbon content combined with high chromium/nickel/molybdenum amount results in soft material with high resistance to machining and a low machinability rating of 38%.

The main challenge in machining austenitic stainless is the low carbon content combined with high chromium/nickel content. The result is a soft material with high resistance to machining. Because of the high ductility, you should generally opt for a sharp and positive cutting edge. In turning operations, one of the most common reasons for short tool-life is notch wear forming at the depth of the cut line, which results in a large burr forming on the workpiece. The best method to prevent notch wear is to change the depth of the cut constantly.

Summery:

For general Turning of Stainless Steel 317 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 Below Chart, or use the Grades Wizrad.

Recommended Cutting speed range for turning at stable conditions is 460 - 620 [SFM] / 140 - 190 [m/min].

Recommended Cutting speed range for milling with stable clamping and short overhang is 300 - 390 [SFM] / 90 - 120 [m/min]
