Indian standard for sheet metal thickness tolerance.

Astm a240 a480 steel sheet sthickness tolerance. 8 1 the rolling and cutting tolerances and mass tolerances for steel plates sheets strips and. 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. After the draft finalized by the wrought steel products sectional committee had been approved by the metallurgical engineering division council.

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. This indian standard sixth revision was adopted by the bureau of indian standards.

Itcovers sheets and strips up to 4 50 mm thick both in coil form and cut lengths. Title of legally binding document. Astm a480hot rolled sheet coil thickness tolerance. 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.

The following are the preferred thicknesses for sheets above 2 00 mm. 2005 continuously hot rolled steel sheet products dimensional and shape tolerances. This standard was first published in 1951 and subsequently revised in 1962.
