Finally the hardness requirements for different grades of tubes are highlighted. Combining values from the two systems may result in non-conformance with the standard. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or aa269 to date. Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse flattening test are presented.
These grades cannot be hardened by thermal treatment. It is extremely ductile, with excellent strength at elevated temperatures.
A Stainless Steel Tubes Coating. Historical Version s – view previous versions of standard. Q269 to Active This link will always route to the current Active version of the standard. Background of L Stainless Steel Pipes and Tubes Grade is the standard molybdenum-bearing grade, second in importance to amongst the austenitic stainless steels. ASTM A Seamless Tubes are manufactured using supreme grade asm elements, thus ensuring hardness and chemical resistance.
This specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service. Ksi MPaMin.
This is particularly associated with crevices and rough surface finish. These comparisons are approximate only.
All material shall be furnished in the heat-treated condition. Typical physical properties for grade stainless steels. Thus it is extensively used in heavy gauge welded components over about 6mm. The list is intended as a comparison of functionally similar materials not as aztm schedule of contractual equivalents.

Grade also has outstanding welding characteristics. It is extremely ductile, with excellent strength at elevated temperatures.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. It is less expensive than seamless or welded-and-drawn a69. 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.
ASTM A269 Specifications
The steel shall conform to the chemical composition requirements. SS Seamless Tube can be produced with heavier wall thicknesses for mechanical applications. Also, each astm a tube shall be subjected to the non-destructive electric test or the hydrostatic test. Composition ranges for grade of stainless steels.
This abstract is a brief summary of the referenced standard. Our offered ASTM A Specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service.
