2、ion. 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 U.S. Department of Defense.1. Scope*1.1 This specification covers hot-finished or
3、 cold-finished bars except bars for reforging (Note 1). It includes rounds, squares,and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainlesssteels. The free-machining types (Note 2) for general corrosion resistance and high-temp
4、erature service are covered in a separatespecification.NOTE 1For bars for reforging, see Specification A314.NOTE 2For free-machining stainless bars designed especially for optimum machinability, see Specification A582/A582M.NOTE 3There are standards covering high nickel, chromium, austenitic corrosi
5、on, 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 separately as standard. Within the text, the SI
6、unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems may result in non-conformance with the standard. Theinch-pound units shall apply unless the “M” designation
