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. [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. ASTM A6 - American Welding SocietyJul 15, 2012 · During the receipt of a carbon steel plate of 25mm thickness were asked to calculate the maximum flatness and waviness knowing that, a specification ASTM A36 sheared edges, dimensions of 9000.0 mm x 2400.0 mm? how to check flatness and waviness in ASTMA6 ? By G.S.Crisi Date 06-30-2012 17:20 ASTM A36 makes part of ASTM A6.
Width governs the tolerances both width and thickness for rectangle bars. If the bar is 1.5" thick x 3.5" wide, the width tolerance of +/-0.006" will be the tolerance for the thickness as well, which is +/-0.006". Flatness In Steel & What To Expect Clifton SteelAlthough ASTM is the most widely used specification for flatness, some products have developed their own flatness specs, so a review of the spec you are using is advised. Below is an example of part of the ASTM A6 commercial standards for heat treated plate. Contact us for further information on flatness tolerances. HOT ROLLED - AK SteelThickness, width, and flatness tolerances are covered in ASTM A568 or A635. 3 HOT ROLLED STEELS Tables TABLE 1 TYPICAL MECHANICAL PROPERTIES STANDARD GRADES Quality Designation Description Grade 36 (Type 2) For conversion to A36 36 250 58 - 80 400 - 550 20 21 19 Grade 40 40 275 55 380 20 21 21
Flatness tolerances other than the above must be agreed at the time of enquiry and order. For further information, contact:ArcelorMittal South Africa Limited, PO Box 2, Vanderbijlpark 1900. Toll free number 0800 005043 Care has been taken to ensure that the information in this data sheet is accurate. ArcelorMittal South Africa Limited does not Plate and Sheet Flatness - Rolled Alloys, Inc.The flatness requirements in ASTM A 480, for plates produced to A 240, were simplified recently to a 36 rule. The method of measurement is to place the 36 rule on the concave side so both ends of the rule are in contact with the plate surface. Reasonable tolerancing for press brake bendingSep 11, 2018 · For instance, typical 10-ga. A36 material has a gauge-zone tolerance of ±0.006 in. This means that 10-ga. can be anywhere from 0.129 to 0.141 in. That 0.012-in. difference may not seem like much, but when it comes to forming on the press brake,
However, particular flatness and parallelism values are not guaranteed. 2.50 x 24.00 x 36.00, A36, Flame cut and cleaned, Stress Relieved, Blanchard Ground to 2.250 (+/-0.010) When the part will be bolted or welded to another surface, flatness is not as important to specify. astm a6 flatness tolerance - aipg.roSize ( in. plates, Shapes, and sheet piling ( astm a6 flatness tolerance sheet..
