The analysis shall meet the requirements of Table 1. Mechanical Properties Requirements 7. 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 astmm 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.
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. H Elongation in 2 in. 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.
J Annealed bars shall be capable of meeting the tempered condition requirements when heat treated. 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. Thank you for interesting in our services. F Tensile strength 70 ksi [ MPa] min permitted for extruded shapes.
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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Originally approved in 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.

Tests shall be performed in accordance with Practice E of Practices A This standard has been approved for use by agencies of the Department of Defense. Combining values from the two systems may result in non-conformance with the standard. We are a non-profit group that run this website to share documents.

Approved November 1, If you feel that your comments have not received a fair hearing you should make your views known to awtm ASTM Committee on Standards, at the address shown below.
All austenitic stainless steels shall be capable of passing intergranular corrosion tests in the as-shipped condition. Historical Version s – view previous versions of standard. A number in parentheses indicates w479 year of last reapproval. Combining values from the two systems may result in non-conformance with the standard.
NOTE 2—Many, if not all, asmt 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.
Austenitic Grades N Alloy 20 0.

B Maximum unless otherwise indicated. S S S S The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Link to Active This link will always route to the current Active version of the standard. A49 For bars greater than 2 in.
Please fill this form, we will try to respond as soon as possible. The test method sreporting requirements, and acceptance criteria shall be agreed upon by the manufacturer and purchaser in the purchase agreement.

Permission rights to photocopy the standard may also be secured from the ASTM website www. This abstract is a brief summary of the referenced standard.
Bars furnished in lengths of 20 ft [6 m] and over shall be tested at each end. Four grades of the stainless steel are available which includes austenitic, austenitic-ferritic, ferritic, and martensitic grades. 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.
This specification covers hot- and cold-finished bars of stainless steel, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction. Such testing may or may not be routinely performed by the manufacturer. The certification shall be positively relatable to the lot of material represented. 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.
H Product analysis tolerance over the maximum limit for carbon and nitrogen to be 0. Mechanical properties such as tensile strength, yield strength, elongation, and hardness shall be determined for the specimens subjected to normalized, tempered, annealed, and quenched conditions.
