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.

Stainless Steel ASTM A479 Round Bars Supplier
Note 1—There are standards covering zstm nickel, chromium, austenitic corrosion, and heat-resisting alloy materials. Please help us to share our service with your friends. Link to Active This link will always route to the current Active version of the adtm. Reduction of area does not apply on? Current edition approved Nov.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Proceed to Checkout Continue Shopping. Approved November 1, E See Supplementary Requirement S1. These phases can typically be removed by correct annealing and cooling practices. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
In the event of failure, asrm lot represented shall be rejected except that, at the option of the manufacturer, each bar in the lot may be tested for acceptance.
Product analysis tolerance provisions do not apply.

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. Grain Size for Austenitic Grades 6. F For bars greater than 2 in.

The grain size shall be reported on a Certi?
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 for different alloy grades. H Elongation in 2 in.
J Annealed bars shall be capable of meeting the tempered condition requirements when heat treated. As the voice of the U. 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.
We have no amendments or corrections for this standard.
I Elongation in 2 in. G For bars greater than 2 in. All austenitic stainless steels shall be capable of passing intergranular corrosion axtm in the as-shipped condition. Straightening is permitted as a?
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 analysis shall meet the requirements of Table 1.
Mechanical Properties Requirements 7. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
For that reason, a minimum grain size has been required of the H z479 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. It is informational only and not an official part of xstm standard; the full text of the standard itself must be referred to for its use and application.
Originally approved in D See Supplementary Requirement S1. 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.
B Maximum unless otherwise indicated. C Except as required for speci? This standard has been approved for use by agencies a749 the Department of Defense. F Tensile strength 70 ksi [ MPa] min permitted for extruded shapes. XM Up to 2 in. Heat treatment requirements added to 4. Add to Alert PDF. Bars furnished in lengths of 20 ft [6 m] and over shall be tested a4799 each end.
Such testing may or may not be routinely performed by the manufacturer. Originally approved in Approved May 1, 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 speci? The certification shall be positively relatable to the astmm of material represented. Testing for Intermetallic Compounds 9.
These phases can have a negative effect on mechanical properties and corrosion resistance. The test method sreporting requirements, and acceptance criteria shall be agreed upon by the manufacturer and purchaser in the purchase agreement. E American Welding Society designation. Need more than one copy? The analysis shall meet the requirements of Table 1. B Maximum unless otherwise indicated.
