1、Designation:A479/A479M13A479/A479M13a Used in USDOE-NE Standards Standard Specication for Stainless Steel Bars and Shapes for Use in Boilers and Other Pressure Vessels 1 This standard is issued under the xed designationA479/A479M; the number immediately following the designation indicates the year o

2、f original adoption or, in the case of revision, the year of last revision.Anumber 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

3、 of Defense. 1. Scope* 1.1 This specication 2 covers hot- and cold-nished bars of stainless steel, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction. 2 NOTE 1There are standards covering hi

4、gh nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. These standards are under the jurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM Standards, Vol 02.04. 1.2 The values stated in either SI units or inch-pound units are to be regarded separate

5、ly as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 Unless the order species the applicable M specication designation

6、, the material shall be furnished to the inch-pound units. 2.
