Astm sheet metal thickness tolerance chart.

Sheet metal guage tolerances. Thickness measurements are taken at least 3 8 inch in from edge of the strip except that on widths less than 1 inch the tolerances are applicable for measurements at all locatons. Above tolerances include crown. Mechanical steel sheet mechanical tolerances.

Astm a480hot rolled sheet coil thickness tolerance. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. 254 0mm excl in thickness the tolerance under the specified thickness is 0 010 in. Astm s steel standards are instrumental in classifying evaluating and specifying the material chemical mechanical and metallurgical properties of the different types of steels which are primarily used in the production of mechanical components industrial parts and construction elements as well as other accessories related to them.
