1、Designation: A595/A595M 11Standard Specification forSteel Tubes, Low-Carbon or High-Strength Low-Alloy,Tapered for Structural Use1This standard is issued under the fixed designation A595/A595M; the number immediately following the designation indicates the yearof original adoption or, in the case of
2、 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 Department of Defense.1. Scope*1.1 This specific
3、ation covers three grades of seam-welded,round, tapered steel tubes for structural use. GradesAand B areof low-carbon steel or high-strength low-alloy steel composi-tion and Grade C is of weather-resistant steel composition.1.2 This tubing is produced in welded sizes in a range ofdiameters from 238
4、to 30 in. 60 to 762 mm inclusive. Wallthicknesses range from 0.1046 to 0.375 in. 2.66 to 9.53 mm.Tapers are subject to agreement with the manufacturer.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exa
5、ct equivalents; therefore, eachsystem shall be used indepedently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2.
