Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
A number in parentheses indicates the year of last reapproval. A Samples for testing shall be in the form of a section not exceeding 3? The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test. Please first verify your email before subscribing to alerts.
A4779 values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Bars furnished in lengths of 20 ft [6 m] and over shall be tested at each end. All austenitic stainless steels shall be capable of passing intergranular corrosion tests in the as-shipped condition. Link to Active This link will always route to the current Active version of the standard.

Already Subscribed to this document. I Elongation in 2 in. In the event of failure, the lot represented shall be rejected except that, at the option of the manufacturer, each bar in the lot may be tested for acceptance.
Four grades of the stainless steel are available which includes austenitic, austenitic-ferritic, ferritic, and martensitic grades. D See Supplementary Requirement S1. NOTE 2—Many, if not all, duplex stainless steels and some austenitic stainless steels will axtm intermetallic phases or compounds such as sigma, chi, and laves phases when exposed to temperatures below the specified annealing temperature or cooled slowly from a higher temperature during casting, welding, aatm annealing.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. I Elongation in 2 in. J Annealed bars shall be capable of meeting the tempered condition requirements when heat treated. For that reason, a minimum grain size has been required of the H grades created for optimum elevated temperature propertiesand a mandatory grain size test and report has been added for the non—H grades so that the information is available for those desiring to reclassify a non—H grade to H grade.
