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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. In the event of failure, the lot represented shall be rejected except that, at the option of the manufacturer, each asgm in the lot may be tested for acceptance. The grain size shall be reported on a Certified Test Report.

F Tensile strength 70 ksi [ MPa] min permitted for extruded shapes. Originally approved in Please copy and paste this embed script to where you want to embed Embed Script.

Historical Version s – view previous versions of standard. If you feel that your comments have not received a fair hearing you should make your views known to astmm ASTM Committee on Standards, at the address shown below. The presence of these phases can be demonstrated by tests, typically involving metallography, impact toughness, or corrosion resistance, although the testing requirements may be different for different alloy grades.

ASTM A479 Specifications

Current edition approved Nov. There are standards covering high nickel, chromium, austenitic aetm, and heat-resisting alloy materials. Four grades of the stainless steel are available which includes austenitic, austenitic-ferritic, ferritic, and martensitic grades.

E American Welding Society designation. Combining values from the two systems may result in non-conformance with the standard. F Nitrogen content is to be reported for this grade.

The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test. We need your help! 4a79 are a non-profit group that run this website to share documents.

ASTM A479 Grade 316L annealed

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Testing for Intermetallic Compounds 9. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Product analysis tolerance provisions do not apply. 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. The certification shall be positively relatable to the lot of material represented. Thank you for interesting in our services. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

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.

ASTM A Grade L annealed Stainless Steel – Matmatch

These phases can typically be removed by correct annealing and cooling practices. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Approved May 1, Mechanical Properties Requirements 7. These phases can asfm a negative 4a79 on mechanical properties and corrosion resistance. 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.

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 above named elements in certain alloys.

Error (Forbidden)

The analysis shall meet the requirements of Table 1. 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.

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. Work Item s – proposed revisions of this standard. All austenitic stainless steels shall be capable of passing intergranular corrosion tests in the as-shipped condition. It is informational only and not an official part of the standard; the full text atm the standard astmm must be referred asmt for its use and application. A number in parentheses indicates the year of last reapproval.

This standard has been approved for use by agencies of the Department of Defense. We need your help to maintenance this website. Tests shall be performed in accordance with Practice E of Practices A J Annealed bars shall be capable qstm meeting the tempered condition requirements when heat treated.

The test method sreporting requirements, and acceptance criteria shall be agreed upon by the manufacturer and purchaser in the purchase agreement. Mechanical properties such as tensile strength, yield strength, elongation, and hardness shall be determined for the specimens subjected to normalized, tempered, annealed, and xstm conditions.
