Astm Sheet Metal Tolerances

Astm a36 steel plate is a structural quality mild carbon steel used in general construction applications including bolted or welded construction of buildings bridges and common machine parts.

The following charts give typical astm and ansi steel sheet mechanical tolerance ranges. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances.

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.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Table a2 8 permitted variations in flatness of cold rolled wide coil processed product as cut lengths. Astm ansi mechanical steel sheet mechanical tolerances. Tolerance below apply to the following alloys.

Sheet metal guage tolerances. Because of tolerances ie astm a36 steel plate thickness tolerance flatness and camber as well as the hot roll condition astm a36 steel plate generally does not finish to specified thickness.
