Stainless Steel Plate Flatness Tolerance

Specifications a 480 and ams 2242 cover many of the stainless steel flat products.
Stainless steel plate flatness tolerance. These are steel types l and h. For material longer than 10 the variation in flatness for any 10 feet of length should not exceed the amount shown. Flatness tolerances for sheet are published only for full size sheets. Permitted variations in flatness of plate mill plate quarto plate note 1 tolerances in this table apply to any length not necessarily the rolling direction up to 36 in.
914mm and to any 36 in. L products with a specified minumum yield strength 460 n mm2 neither quenched nor quenched and tempered. Flatness tolerances listed are of roller leveled sheets or plates with no or min imum margins. With its larger demand in soft tempers precision steel provides a tolerance data sheet for 304 annealed stainless steel.
Furthermore it gives a few real world examples of who is using this process and what they are saying about it. 914mm of longer lengths in the plane of the plate measured while the plate rests on a flat surface with the concavity of the curvature upward. The tolerance also depends on the minimum yield strength of the steel. Over 12 to 24 excl 005 to 010 incl.

Flatness tolerances are either normal class n or special class s. For material 10 or less in length variation should not exceed amount shown in table.
This article examines flatness of steel discussing the outcome of combining temper passing and leveling in the same line. 914 mm and to any 36 in. It also provides the outcomes of experimentation on steel that has been leveled temper passed and both. It is important to remember that these tolerances apply to the mill produced product where they have specialized equipment to perform flattening operations.
