1、Designation: A582/A582M 121Standard Specification forFree-Machining Stainless Steel Bars1This standard is issued under the fixed designation A582/A582M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A n
2、umber 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.1NOTESection 4.1 was editorially updated in October 2012.1. Scope*1
3、.1 This specification covers hot-finished or cold-finishedbars, except bars for forging (Note 1), suitable for machiningprocesses. It includes rounds, squares, and hexagons in themore commonly used types of stainless free-machining steelsdesigned especially for optimum machinability and for generalc
4、orrosion and high-temperature service. Stainless steel barsother than the free-machining types are covered in a separatespecification (Note 2).1.2 This specification is expressed in both inch-pound unitsand in SI units; however, unless the purchase order or contractspecifies the applicable M specifi
5、cation designation (SI units),the inch-pound units shall apply. The values stated in eitherinch-pound units or SI (metric) units are to be regardedseparately as standard: within the text and tables, the SI unitsare shown in brackets. The values stated in each system maynot be exact equivalents: ther
6、efore, each system shall be usedindependently of the other. Combining values from the twosystems may result in nonconformance with the specification.NOTE 1For bars for reforging, see Specification A314.NOTE 2For non-free machining stainless bars, see SpecificationA276.2.
