Mild steel plate thickness tolerance.
During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
Highlighted red area refers to plates produced in their flat form for which the listed tolerances are only the over 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.
Sheet metal guage tolerances.
It s often used as wear strips liners and deflector plates.
These precision ground sheets and bars are held to a tight thickness tolerance.
B for plates up to 10 in.
Tight tolerance multipurpose oil hardening o1 tool steel.
For steel type l a maximum of 1 and for steel type h a maximum of 1 5 of the distance between points of contact on the plate between 300 and 1000mm but not exceeding the values in the above table.
Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Tolerance under specified thickness 010 x 3 4 x 52 wide plate for example would have a tolerance range of 740 780 because of tolerances ie thickness flatness and camber as well as the hot roll condition astm a36 generally does not finish to specified thickness.
Also known as mild steel low carbon steel is easy to machine form and weld.
9 52 mm but not more than 3 in.
Meter of hot rolled mild steel plates can be calculated as.
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.

Steel sheets and plates are typical stocked as size 2000 mm x 3000 mm.
Thickness is measured at any point more than 25mm from any edge excluding ground areas.
