Indian Standard For Sheet Metal Thickness Tolerance

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.

Indian standard for sheet metal thickness tolerance.

G requirements of dimensions and tolerances have been separated from the standard and adopted in is iso 16160. After the draft finalized by the wrought steel products sectional committee had been approved by the metallurgical engineering division council. General tolerances part 1. Legally binding document step out from the old to the new jawaharlal nehru invent a new india using knowledge.

This standard was first published in 1951 and subsequently revised in 1962. Title of legally binding document. This indian standard sixth revision was adopted by the bureau of indian standards. 2005 continuously hot rolled steel sheet products dimensional and shape tolerances.

The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker. Itcovers sheets and strips up to 4 50 mm thick both in coil form and cut lengths. Astm a480hot rolled sheet coil thickness tolerance. Thickness 5 mm and above and width 600 mm and above and supplied in straight lengths.

Deviation allowed for the specified width. For ail the tests specified in this standard chemical physical others the method as specified in. The following are the preferred thicknesses for sheets above 2 00 mm. 8 1 the rolling and cutting tolerances and mass tolerances for steel plates sheets strips and.

Strip can be supplied in mill edge finish or with edges suitably sheared width having maintained within tolerance limits and both the edges running parallel plates can also be supplied identically with mill edge finish or with sheared edges. 2 50 mm 2 65 3 00 3 25 3 50 mm and 4 00 mtn. Indian standard cold reduced low carbon steel sheet and strip fifth revision 1 scope 3 classification ofgrades this standard covers the requirements ofcold reduced low carbon steel sheets and strips for bending and drawing purpose and where the surface is ofprime importance. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
