Mild Steel Plate Thickness Tolerance

Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric.
Mild steel plate thickness tolerance. These precision ground sheets and bars are held to a tight 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. A thickness is measured along the longitudinal edges of the plate at least 3 8 in. 9 52 mm but not more than 3 in.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. W 7 85 t 2 where. Tight tolerance multipurpose oil hardening o1 tool steel. 76 20mm from the edge.
B for plates up to 10 in. Special flatness tolerances class s. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. A1 4 plate mill product tolerances hot rolled steel plate.
Also known as mild steel low carbon steel is easy to machine form and weld. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. W weight of steel plate kg m 2 t plate thickness mm steel plate weight calculator metric units. Width mm length mm thickness mm density kg m 3.
The permissible under thickness is 0 3 mm for all dimensions. Highlighted red area refers to plates produced in their flat form for which the listed tolerances are only the over thickness tolerance. Steel sheets and plates are typical stocked as size 2000 mm x 3000 mm. 254 0 mm excl in thickness the tolerance under the specified thickness is 0 010 in.
Sheet metal guage 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. Actual thickness will vary due to tolerances. 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.
It s often used as wear strips liners and deflector plates. Meter of hot rolled mild steel plates can be calculated as.
