标准简介
OVERVIEW中文简介
本规范适用于热加工或冷加工的易切削不锈钢棒材，不包括锻造用棒材。涉及圆形、方形和六角形等截面，材料旨在兼顾切削加工性能及一般耐腐蚀和高温使用要求。文件规定了订货信息、交货通用要求、供货状态、化学成分、硬度试验及按采购要求提供的认证资料，并以表格列出相关钢种的化学成分和机械试验要求。英制与国际单位制分别使用，不能混合使用两套数值。
English summary
This specification covers hot-finished or cold-finished free-machining stainless steel bars, excluding bars for forging. It includes round, square and hexagonal sections intended for machinability and general corrosion and high-temperature service. Requirements address ordering information, general delivery requirements, supply condition, chemical composition, hardness testing and certification when requested by the purchaser. Tables specify chemical requirements, conditions and mechanical test requirements for the covered grades. Inch-pound and SI values are treated as separate systems and must not be combined.

Designation: A 582/A 582M – 95b (Reapproved 2000)
Standard Specification for
Free-Machining Stainless Steel Bars1
This standard is issued under the fixed designation A 582/A 582M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. 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.
