Astm sheet metal tolerances.

1 1 this specification covers the general requirements for steel sheet in coils and cut lengths. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. 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. 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.

Astm a480hot rolled sheet coil thickness tolerance. Table a2 8 permitted variations in flatness of cold rolled wide coil processed product as cut lengths. 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. The following charts give typical astm and ansi steel sheet mechanical tolerance ranges.
