We would prefer if all plate and sheet were flat.Unfortunately,the reality is quite different and the standard commercial specifications to which these products are produced recognize this reality.The requirements on the flatness of the plate and sheet products sold by Rolled Alloys vary considerably by the type of product,by alloy,by thickness and by the size of the piece.AMS and ASTM standards exist whPublicationAdvantagesPurposeExampleCostFlatness tolerances for sheet are published only for full size sheets.Since Rolled Alloys also levels this product,we work to the mill tolerances.In general,sheets 60 wide and under are to be no more than ½ out of flat when laid on a flat surface.See more on rolledalloysExplore furthersp.infoFlatness In Steel What To Expect Clifton SteelcliftonsteelSTANDARD ASTM MILL TOLERANES FLATNESScmgmetalsPermitted Variations in Flatness of Plate Mill Plate sandmeyersteelASTM A36 steel plate thickness tolerance steel plate,ASTM steel-plate-sheetStainless Steel Sheet and Plate TolerancesFinal - RyersonryersonRecommended to you based on what's popular • FeedbackHow important is sheet and plate steel flatness?
Mar 14,2002·In its natural state,steel is not at all flat.In fact,a hot-rolled sheet coil generally reveals some or all symptoms of poor flatness (see Figure 1 ).For example,72-inch-wide material with a 100,000-PSI yield strength can have a crossbow of 2 to 12 in.,wavy edges,and excessive crown.These shape imperfections must be removed to produce a

FLATNESS TOLERANCEsp.infoFLATNESS TOLERANCE The maximum deviation from a horizontal flat surface—the material is to be placed on a perfectly flat table.A ruler which does not flatten the material will give the degree of flatness.The measurement being from the highest point (or points) of the sheet or plate to the table surface minus the material thick-ness.Steel Plate Sheet - Grades Finishes Steel Supply,L.P.
