Steel Sheet Tolerances Thickness

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Steel sheet tolerances thickness.

4 20 2009 11 06 42 am. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Sheet metal guage tolerances. Stainless sheet thickness tolerances.

However the range of tolerance on hot rolled sheet is much wider than the range found on cold rolled sheet. Thickness is measured along the longitudinal edges of the plate at least 3 8inches but not more than 3 inches from the edge. Stainless steel sheets sizes in stock. Stainless sheet thickness tolerances xls author.

Above tolerances include crown. The range of the tolerance minimum thickness to maximum thickness in each gauge range decreases as the sheet material becomes thinner on its nominal or mean thickness. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. You can use this sheet metal data table for all the common commercial grades of stainless steel such as 304 316 and 430.

Thickness measurements are taken at least 3 8 inch in from edge of the strip except that on widths less than 1 inch the tolerances are applicable for measurements at all locatons. These are the most common grades asked for by our customers when wanting sheet metal fabrications. Stainless steel sheet forms finishes and tolerances ati sheet stainless steels are flat rolled products produced by continuous mill rolling available in coils or cut lengths. Thicknesses range from 0 018 to 0 1874 and widths range from 24 to 48.

Both types of steel sheet have tolerance ranges. For plates up to 10 inches excl in thickness the tolerance under the specified thickness is 0 010. Sheet metal thickness tolerances for austenitic ferritic and martensitic stainless steels. For thicknesses lighter than 0 018 refer to the mill.
