MACHINABILITY OF 6150 STEEL
Steel 6150 is a low-alloy steel with a carbon content of 0.5% and additional 2% content of manganese, chromium, and vanadium. (See details in the table below). Steel 6150 has a machinability rating of 60%.
Low alloy steels are very popular in machine shops. The small amount of alloying elements enhances their mechanical properties and hardenability without a significant sacrifice in terms of machinability.
SUMMARY:
For general turning of Steel 6150 at stable conditions use a grade with a hard substrate and CVD coating.
In case you are running at a cutting speed that is lower than 490 SFM (150 m/min), it is better to use a grade with a 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 740 - 1000 [SFM] / 225 - 305 [m/min].
Recommended Cutting speed range for milling with stable clamping and short over hang is 460-620[SFM]/140-190[m/min]
For detailed cutting speed recommendations,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.
