E American Welding Society designation.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. S S S S Tests shall be performed in accordance with Practice E of Practices A 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.

Such testing may or may not be routinely performed by the manufacturer. 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. Grain Size for Austenitic Grades 6.

D See Supplementary Requirement S1. I Elongation in 2 in. Work Item s – proposed revisions of this standard.

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. Approved May 1, The analysis shall meet the requirements of Table 1.

ASTM A479 Grade 410 annealed

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. These phases can have a negative effect on mechanical properties and corrosion resistance. Please fill this form, we will try to respond as soon as possible.


qstm The grain size shall be reported on a Certified Test Report. Combining values from the two systems may result in non-conformance with the standard. The test method sreporting requirements, and acceptance criteria shall be agreed upon by the manufacturer and purchaser in the purchase aetm. 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. Austenitic Grades N Alloy 20 0.

H Elongation in 2 in.

ASTM A Grade L annealed Stainless Steel – Matmatch

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Please copy and paste this embed script to where you want to embed Embed Script. B Maximum unless otherwise indicated.

This specification covers hot- and a79 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. F Tensile strength 70 ksi [ MPa] min permitted for extruded shapes.

Permission rights to photocopy the sstm may also be secured from the ASTM website www. These phases can typically be removed by correct annealing and cooling practices.


All austenitic stainless steels shall be capable of passing intergranular corrosion tests in the as-shipped condition. Materials for High-Temperature Service S1. Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard.

This standard has been approved for use by agencies of the Department of Defense.

A number in parentheses indicates the year of last reapproval. 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.

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.

ASTM A479 Grade 316L annealed

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.

Size px x x x x Current edition approved Nov. The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test.

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.

F Nitrogen content is to be reported for this grade. Please help us to share our service with your friends. We need your help to maintenance this website. J Annealed bars shall be capable of meeting the tempered condition requirements when heat treated. There are standards covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials.
