1、Designation: A 582/A 582M 05Standard Specification forFree-Machining Stainless Steel Bars1This standard is issued under the fixed designation A 582/A 582M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision.

2、A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers hot-finished or cold-fin

3、ishedbars, 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 generalcorrosion and high-temperature service.
