MACHINABILITY OF 5132 STEEL
Steel 5132 is a low-alloy steel with a carbon content of 0.3% and additional 1.6% content of manganese, chromium. (See details in the table below). Steel 5132 has a machinability rating of 77%.
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 5132 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 930 - 1280 [SFM] / 285 - 390 [m/min].
Recommended Cutting speed range for milling with stable clamping and short overhang is 590-790[SFM]/180-240[m/min]

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.
