General Information for Material Discaloy 16
||S - Superalloys (Heat resistant and Titanium)
MACHINABILITY OF DISCALOY 16 MATERIAL
Discaloy 16 is an Iron-based heat resistant superalloy (HRSA) material with a Machinability rating of 40% and Hardness of 290 HB.
Discaloy 16 has 50.1% iron, 25% nickel and additional alloying elements per the below table.
Iron-based superalloys are a more economical alternative to nickel-based alloys. They provide the same advantages but to a lesser extent and at a lower price. They are used mostly on less critical components that still require heat resistance properties. This sub-group is also much easier to machine relative to the nickel and cobalt based superalloys
Superalloys should be machined with a positive and sharp cutting edges. Geometries that are suitable for austenitic stainless steel will also work well on HRSA. However, quality manufacturers will have in their catalogs additional geometries that are specifically designed for these challenging materials.
For general turning of material discaloy 16 at stable conditions use a grade with a very hard substrate and thin PVD coating.
For general milling use a grade with a semi hard substrate and PVD coating.
For detailed carbide grades recommendations, check the table below.
Recommended Cutting speed range for turning at stable conditions is 440 - 610 [SFM] / 135 - 185 [m/min].
Recommended Cutting speed range for milling with stable clamping and short overhang is 330 - 460 [SFM] / 100 - 140 [m/min]
For detailed cutting speed recommendations, check the table below.
