Astm Sheet Metal Tolerances

The following charts give typical astm and ansi steel sheet mechanical tolerance ranges.

Astm sheet metal 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.

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. Astm a480hot rolled sheet coil thickness tolerance. It applies to the following specifications that describe carbon steel structural steel and high strength low alloy steel hsla furnished as hot rolled sheet and cold rolled sheet.
