Different mechanical test requirements that includes, flaring test, flange astn, hardness test, and reverse flattening test are presented. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. It is extremely ductile, with excellent strength at elevated temperatures. With the addition of molybdenum, the steel is popular for use in severe corrosion environments due to the materials immunity from boundary carbide precipitation sensitisation.
ASTM A269 / ASME A269
Historical Version s – view previous versions of standard. SS Seamless Tube can be produced with heavier wall thicknesses for mechanical applications.
All material shall be furnished in the ashm condition. If exact equivalents are needed original specifications must be consulted. 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. A Stainless Steel Tubes Coating. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Specification Tolerances for ASTM A
The ASTM A specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service. It has excellent forming and welding characteristics. In many marine environments does exhibit surface corrosion, usually visible as brown staining. It is ideal for hydraulic and instrumentation tubing in chemical, textile, and pulp and paper industries, and in marine environments.
Clear labels are tagged on the outside of the package for easy identification of the quantity and product I. Thus it is extensively used in heavy gauge welded components over about 6mm. Typical physical properties for grade stainless steels. Ksi MPaMin. Home About Site Map Resource. The steel shall conform to the chemical composition requirements.
The material is widely used in heavy gauge welded components and weld annealing is only required where the material is for use in high stress environments.
ASTM A Seamless Tubes are manufactured using supreme grade alloying elements, thus ensuring hardness and chemical resistance. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Also, each astm a tube shall be subjected to the non-destructive electric test or the hydrostatic test. Mechanical properties of grade stainless steels.
Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about C. Within days or asap if we have enough stock. This abstract is a brief summary of the referenced standard.
Upon completion, all material shall:.
The list is intended as a comparison of functionally similar z269 not as a schedule of contractual equivalents. It is extremely ductile, with excellent strength at elevated temperatures. This specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service.
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.
Finally the hardness requirements for different grades of astm a tubes are highlighted. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
