2、the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1
3、.1 This specification2 covers carbon steel plates of low- and intermediate-tensile strengths which may be made by killed,semi-killed, capped, or rimmed steel practices at the producerskilled or semi-killed at the producers option. These plates areintended for fusion-welded pressure vessels.1.2 Plate
4、s under this specification are available in three grades having different strength levels as follows:Grade Tensile Strength, ksi MPaA 4565 310450B 5070 345485C 5575 3805151.3 The maximum thickness of plates under this specification, for reasons of internal soundness, is limited to a maximumthickness
5、 of 2 in. 50 mm for all grades. is limited by the capacity of the composition to meet the specified mechanical propertyrequirements.NOTE 1For killed carbon steels only, refer to the following ASTM specifications:3A 299/A 299M Pressure Vessel Plates, Carbon Steel, Manganese-Silicon.A299/A299M Specifi
