1、Designation: A285/A285M 12A285/A285M 17Standard Specification forPressure Vessel Plates, Carbon Steel, Low- andIntermediate-Tensile Strength1This standard is issued under the fixed designation A285/A285M; the number immediately following the designation indicates the yearof original adoption or, in

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
