MACHINABILITY OF 1049 STEEL
Steel 1049 is a carbon steel material with 0.5% carbon content. Carbon steels range in carbon content between 0.08% to 1%. The machinability is very sensitive to the amount of carbon. Materials with little carbon content (below 0.15%) are too soft and gummy, and materials with a carbon content above 0.5% are harder and thus have lower machinability
Since Steel 1049, has 0.5%, it is relatively easy to machine with a good hardness/mildness balance and a machinability rating of 63%.
SUMMARY:
- For general turning of Steel 1049 atstable conditionsuse 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 770 - 1050 [SFM] / 235 - 320 [m/min].
- Recommended Cutting speed range for milling with stable clamping and short overhang is 480 - 640 [SFM] / 145 - 195 [m/min].
- For detailed cutting speed recommendations, check the table below.
