C Except as required for specific alloy type, molybdenum, titanium, nickel, cobalt, tantalum, nitrogen, and copper need not be reported but shall not be present in other than residual amounts, the intent being to prohibit substitution of one alloy type for another due to absence of control of the asfm named elements in certain alloys. B Maximum unless otherwise indicated. Work Item s – proposed revisions of this standard.

Your comments are invited either for asrm of this standard or for additional standards and should be addressed to ASTM International Asttm. S S S S Please help us to share our service with your friends. J Annealed bars shall be capable of meeting the tempered condition x479 when sstm treated.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. At least one room-temperature test shall be performed by the manufacturer on a sample from at least one bar or shape from each lot of material.

Tests shall be performed in accordance with Practice E of Practices A We are a non-profit group that run this website to share documents. Thank you for interesting in our services. NOTE 2—Many, if not all, duplex stainless steels and some austenitic stainless steels will form 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, or annealing.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Bars furnished in lengths of 20 ft [6 m] and over shall be tested at each end. F Nitrogen content is to be reported for this grade. A4479 American Welding Society designation. Link to Active This link will always route to the current Active version of the standard.


The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

Stabilized grades with columbium or titanium added cannot be handled this way, since they would become destabilized due to columbium or titanium carbide solution, without subsequent reheating. Please fill this form, we will try to respond as soon as possible.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Originally approved in Mechanical properties such as tensile strength, yield strength, qstm, and hardness shall be determined for the specimens subjected to normalized, tempered, annealed, and quenched conditions.

We need your help! Size px x x x x H Elongation in 2 in.

Austenitic Grades N Alloy 20 0. Combining values from the two systems may result in non-conformance with the standard. D See Supplementary Requirement S1. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.


In the event of failure, the lot represented shall be rejected except that, at the x479 of the manufacturer, each bar in the lot may be tested for acceptance. All q479 stainless steels shall be capable of passing intergranular corrosion tests in the as-shipped condition.

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. Such testing may or may not be routinely performed by the manufacturer.

These phases can typically be removed by correct annealing and cooling practices. C The material shall be capable of meeting the required reduction of area where listed, but actual measurement and reporting of the reduction of area are not required unless specified in the purchase order. Please copy and paste this embed script to where you want to embed Embed Script. Approved May 1, H Product analysis tolerance over the maximum limit for carbon and nitrogen to be 0.

G For bars greater than 2 in. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

Thus, solution annealing also can be accomplished for nonstabilized grades by taking advantage of hot rolling temperatures which always exceed solution annealing temperature requirementsmaintaining hot rolling finishing temperatures well above minimum solution annealing requirements, and immediately quenching integral with hot rolling.

There are standards covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials.
