MACHINABILITY OF A106GB STEEL
Steel A106GB is a low-alloy steel with a carbon content of 0.3% and additional 1.7% content of manganese, chromium, nickel, and molybdenum. (See details in the table below). Steel A106GB has a machinability rating of 73%.
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 A106GB at stable conditions use a grade with a hard substrate and CVD coating.
If you are running at a cutting speed lower than 490 SFM (150 m/min), using a grade with a hard substrate and PVD coating is better.
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 890 - 1210 [SFM] / 270 - 370 [m/min].
Recommended cutting speed range for milling with stable clamping and short overhang is 560 - 750 [SFM] / 170 - 230 [m/min]
For detailed cutting speed recommendations, check the table below.
