What is tolerance of steel bar?
The ranges are all +0, all minus, i.e. for a 20mm bar to tolerance class h9 with a tolerance range of 0.052, the tolerance is -0.052/+0, giving an acceptable product size range of 19.948 to 20.000mm.
What do you recommend for tolerance if you are milling a 2 diameter bar?
As you can see in the above table, once bars get larger than 2” in diameter, the tolerance is plus only. This means that steel bars larger than 2″ will always be at least their nominal size, and usually larger. As for straightness, bars are permitted to vary ¼” in every five feet of length.
