Mild Steel Plate Thickness Tolerance

Thickness is measured at any point more than 25mm from any edge excluding ground areas.

Mild steel plate thickness tolerance.

Tight tolerance multipurpose oil hardening o1 tool steel. For thicknesses tolerances applicable where the surface was repaired by grinding refer to en 10163 2 delivery requirements for surface condition of hot rolled steel plates. A thickness is measured along the longitudinal edges of the plate at least 3 8 in. Steel sheets and plates are typical stocked as size 2000 mm x 3000 mm.

A1 4 plate mill product tolerances hot rolled steel plate. Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric. Highlighted red area refers to plates produced in their flat form for which the listed tolerances are only the over thickness tolerance. Special flatness tolerances class s.

Width mm length mm thickness mm density kg m 3. W weight of steel plate kg m 2 t plate thickness mm steel plate weight calculator metric units. B for plates up to 10 in. Actual thickness will vary due to tolerances.

9 52 mm but not more than 3 in. 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. W 7 85 t 2 where. The permissible under thickness is 0 3 mm for all dimensions.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. 254 0 mm excl in thickness the tolerance under the specified thickness is 0 010 in. It s often used as wear strips liners and deflector plates. 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.

76 20mm from the edge. 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. Sheet metal guage tolerances. Meter of hot rolled mild steel plates can be calculated as.

These precision ground sheets and bars are held to a tight thickness tolerance. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
