MACHINABILITY OF 5130 STEEL
Steel 5130 is a low-alloy steel with a carbon content of 0.3% and additional 1.8% content of manganese, chromium. (See details in the table below). Steel 5130 has a machinability rating of 69%.
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 5130 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 840 - 1150 [SFM] / 255 - 350 [m/min].
Recommended Cutting speed range for milling with stable clamping and short over hang is 520-710[SFM]/160-215[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.
