tailieunhanh - Standard Specification for Free-Machining Stainless Steel Bars

This specification covers hot-finished or cold-finished bars, except bars for forging (Note 1), suitable for machining processes. It includes rounds, squares, and hexagons in the more commonly used types of stainless free-machining steels designed especially for optimum machinability and for general corrosion and high-temperature service. Stainless steel bars other than the free-machining types are covered in a separate specification (Note 2). | Designation A582 A582M 12 1 Standard Specification for Free-Machining Stainless Steel Bars1 This standard is issued under the fixed designation A582 A582M the number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision.
