Tolerances of Hot-Rolled Cut-Edge (Including Pickled) and Cold-Rolled Sheet
(Over 12 in. Width)
(Carbon
and High-Strength, Low-Alloy Steel)
(Cut
Lengths Not Resquared)
|
Out-of-square
is the greatest deviation of an end edge from a straight line at right angle
to a side and touching one corner. It
is also obtained by measuring the difference between the diagonals of the cut
length. The out-of-square deviation
is one half of that difference. The
tolerance for all thicknesses and all sizes is 1/16 in./6 in. of width or
fraction thereof. |
