Scope*1.1 This specification2 covers hot- and cold-finished bars of stainless steel, including rounds, squares, and hexagons, andhot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction.2NOTE 1There are standards coverin
4、g high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. These standards are under thejurisdiction 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 separa
5、tely as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 Unless the order specifies the applicable “M” specification design
6、ation, the material shall be furnished to the inch-poundunits.1.4 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International Standards, Guides and Recommendations
