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]
  • For detailed cutting speed recomendations, check the Below Table, or use our Speed and Feed Calculator.
