Indian Standard For Sheet Metal Thickness Tolerance

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.

Indian standard for sheet metal thickness tolerance.

Flats shall be as laid down in is 1852. Deviation allowed for the specified width. Astm a240 a480 steel sheet sthickness tolerance. Itcovers sheets and strips up to 4 50 mm thick both in coil form and cut lengths.

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. 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. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Thickness 5 mm and above and width 600 mm and above and supplied in straight lengths.
