New ASTM A582/A582M 2012 Edition on Standard Specification for Free-Machining Stainless Steel Bars

Monday, April 16th, 2012

ASTM A582/A582M-12, “Standard Specification for Free-Machining Stainless Steel Bars,” has just been released and is available now from Document Center Inc. It covers hot-finished or cold-finished bars, except bars for forging, suitable for machining processes.  Typical applications include bolts, bushings, nuts, shafts, and parts produced on automatic screw machines.

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. Bars may be furnished either hot finished or cold finished in one of the conditions specified.

Materials referenced in ASTM A582 need to adhere to specified chemical composition requirements. At least one hardness testing is made midway between surface and center on each lot to determine that the material conforms to the hardness requirements. Test methods and definition for hardness testing are also included.

The standard is expressed in both inch-pound units and in SI (metric) units.  It and all current ASTM standards, as well as many obsolete revisions, are available from Document Center Inc. at our website, www.document-center.com.  Or consider reaching us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We are your Standards Experts.
