Historical Version s – view previous versions of standard. If exact equivalents are needed original specifications must be consulted. It is extremely ductile, with excellent strength at elevated temperatures.
The steel shall conform to the chemical composition requirements. Upon completion, all material shall:. 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. Small outside diameter tubes are defined as those with wstm than 0.
Also, each astm a tube shall be subjected to the non-destructive electric test or the hydrostatic test. Link to Active This link will always route to the current Active version of the standard. In many marine environments does exhibit surface corrosion, usually visible as brown staining. It is extremely ductile, with excellent strength at elevated temperatures. Composition ranges for astn of stainless steels.
Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse flattening test are presented. Post-weld annealing is not required when welding thin sections.

Clear labels are tagged on the outside of the package for easy identification of the quantity and product I. Grade specifications for grade stainless steels. SS Seamless Xstm can be produced with heavier wall thicknesses for mechanical applications. The molybdenum gives better overall corrosion resistant properties than Gradeparticularly higher resistance to pitting and crevice corrosion in chloride environments.
Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used a2269 of the other.
ASTM A269 Specifications
Mechanical properties of grade stainless steels. 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. Corrosion Resistance of L Stainless Steel Pipes and Tubes excellent in a range of atmospheric environments and many corrosive media – generally more resistant than Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about Ast.
Thus it is extensively used in heavy gauge welded components over about 6mm. 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.
Also, each tube shall be subjected to the non-destructive electric test or the hydrostatic test. Finally the hardness requirements for different grades of tubes are highlighted.

ASTM A269 / ASME A269
These comparisons are approximate only. Finally the hardness requirements for different grades of astm a tubes are highlighted. It has excellent forming and welding characteristics. This specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service.
Ksi MPaMin. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided s269 part of 2a69 standard. The list is intended as a comparison of functionally similar materials not as a schedule of contractual equivalents.
The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Grade also has outstanding welding characteristics.
