ASTM A479/A479M : 16a

Standard Specification for Stainless Steel Bars and Shapes for Use in Boilers and Other Pressure Vessels

Standard Details

1.1 This specification2 covers hot- and cold-finished 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 1: There are StandardDetails covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. These StandardDetails are under the jurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM StandardDetails, Vol 02.04.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately 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 specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.
