Application – A is the application of stainless steel just for use in boilers, etc. ASME A is for all applications of stainless steel bars and other shapes. A specifically defers bars for reforging and free machining grades to other ASTM standards (A and A/AM) while A is silent on.

Work Item s – proposed revisions of this standard. J Annealed bars shall be capable of meeting the tempered condition requirements when heat treated.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? 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 a4779 different alloy grades. Approved May 1, The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test.
For that reason, a minimum grain size has been asm 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.
These phases sstm typically be removed by correct annealing and cooling practices. The grain size shall be reported on a Certified Test Report. E See Supplementary Requirement S1.
We have no amendments or corrections for this standard.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Approved March 1, 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.
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. The analysis shall meet the requirements of Table 1. A4799 Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Thus, solution w479 also can be accomplished for nonstabilized grades by taking advantage of hot rolling temperatures which always exceed solution annealing temperature requirementsmaintaining hot rolling?
Mechanical Properties Requirements 7. This standard is also available to be included in Standards Subscriptions. H Product analysis tolerance over the maximum limit for carbon and nitrogen to be 0. E Tensile strength 70 ksi [ MPa] min permitted for extruded shapes. Heat treatment requirements added to 4. Your Alert Profile lists the documents that will be monitored.
Bars furnished in lengths of 20 ft [6 m] and over shall be tested at each end. Bars furnished in lengths of q479 ft [6 m] and over shall be tested at each end. 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.

This specification covers hot- and cold-finished asrm 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.
Approved March 15, We need your help to maintenance this website. 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 atm.
