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. 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. This abstract is a brief summary of the referenced standard. The grain size shall be reported on a Certified Test Report. Four grades of the stainless steel asm available which includes austenitic, austenitic-ferritic, ferritic, and martensitic grades.
ASTM A479 Specifications
Austenitic Grades N Alloy 20 0. If you feel that your comments have not received a fair hearing you should make your views known to axtm ASTM Committee on Standards, at the address shown below. Product analysis tolerance provisions do not apply.
D See Supplementary Requirement S1. The analysis shall meet the requirements of Table 1. 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.
Please copy and paste this embed script to where you want to embed Embed Script. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. G For bars greater than 2 in.
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. Testing for Intermetallic Compounds 9. E American Welding Society designation. Please fill this form, we will try to respond as soon as possible. Combining values from the two systems may result in non-conformance with the standard.
Approved May 1, 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. 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. All austenitic stainless steels shall be capable of passing intergranular corrosion tests in the as-shipped condition.
Please help us to share our service with your friends. The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test.
H Elongation in 2 in.
ASTM A479 Grade 410 annealed
NOTE 2—Many, if not all, duplex stainless steels and some austenitic stainless steels will form intermetallic phases or compounds such as sigma, satm, and laves phases when exposed to temperatures below the specified annealing temperature or cooled slowly from a higher temperature during casting, welding, or annealing. These phases can have a negative effect on mechanical properties and corrosion resistance.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. The certification shall zstm positively relatable to the lot of material represented.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed asttm five years and if not revised, either reapproved or withdrawn. We need your help! A number in parentheses indicates the year of last reapproval. H Product analysis tolerance over the maximum limit for carbon and nitrogen to wstm 0. Combining values from the two systems may result in non-conformance with the 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.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. F Nitrogen content is to be reported for this grade. We are a non-profit group that run this website to share documents.
J Annealed bars w479 be capable of meeting the tempered condition requirements when heat treated. Current edition approved Nov.
Bars furnished in lengths of 20 ft [6 m] and over shall be tested at each end. Grain Size for Austenitic Grades 6. Size px x x x x S S S S Mechanical Properties Requirements 7. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The presence of these phases can be demonstrated by tests, awtm involving metallography, impact toughness, or corrosion resistance, although the testing requirements may be different for different alloy grades.
Such testing may or may not be routinely performed by the manufacturer. There are standards covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. This standard has been approved for use by agencies of the Department of Defense.
