1、Designation: A479/A479M 09Used in USDOE-NE StandardsStandard Specification forStainless Steel Bars and Shapes for Use in Boilers andOther Pressure Vessels1This standard is issued under the fixed designation A479/A479M; the number immediately following the designation indicates the yearof original ad
2、option or, in 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 Department of Defense.1
3、. Scope*1.1 This specification2covers hot- and cold-finished bars ofstainless steel, including rounds, squares, and hexagons, andhot-rolled or extruded shapes such as angles, tees, and channelsfor use in boiler and pressure vessel construction.2NOTE 1There are standards covering high nickel, chromiu
4、m, austen-itic corrosion, and heat-resisting alloy materials. These standards areunder the jurisdiction of ASTM Subcommittee B02.07 and may be foundin Annual Book of ASTM Standards, Vol 02.04.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The v
5、alues stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 Unless the order specifies the applicable “M” specifica-tion designation, the material shal
6、l be furnished to the inch-pound units.2.
