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.

There are standards covering high nickel, chromium, austenitic corrosion, and heat-resisting alloy materials.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Reduction of area does not apply on? 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.
S S S S Approved June 15, The analysis shall meet astn requirements of Table 1. Grain Size for Austenitic Grades 6. Tests shall be performed in accordance with Practice E of Practices A A number in parentheses indicates the year of last reapproval. Four grades of the stainless steel are available which includes austenitic, austenitic-ferritic, ferritic, and martensitic grades. 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.
Work Item s – proposed revisions of this standard.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Originally approved in H Product analysis tolerance over the maximum limit q479 carbon and nitrogen to be 0. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
The certification shall be positively relatable to the lot of material represented.
Combining values from the two systems may result in non-conformance with the standard. E See Supplementary Requirement S1.

This standard has been approved for use by agencies of the Department of Defense. G For bars greater than 2 in. 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. Combining values from a497 two systems may result in non-conformance with the standard.

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. Current edition approved Nov. Subscription pricing is determined by: 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 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. The austenitic stainless steels shall be subjected to heat treatment and shall undergo corrosion test.
