It is ideal for hydraulic and instrumentation tubing in chemical, textile, and pulp and paper industries, and in marine environments.
Thin-wall pipe usually develops significant ovality out-of-roundness during final annealing, straightening, or both. Also, each astm a tube shall be subjected to the non-destructive electric test or the hydrostatic test.
Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse flattening test are presented. 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.
The above tolerances on outside diameter include ovality except for thin-wall pipe. A Stainless Steel Tubes Coating. SS Seamless Tube can be produced with heavier wall thicknesses for mechanical applications. Permissible Variations in Wall Thickness Seamless and welded no filler metal added.

It is extremely ductile, with excellent strength at elevated tplerance. We stocks a wide range of industry standard sizes of both welded and seamless stainless a296 tubes in 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.
ASTM A Seamless Tubes are manufactured using supreme grade alloying elements, thus ensuring hardness and chemical resistance. Finally the hardness requirements for different grades of astm a tubes are highlighted.
Specification Tolerances for ASTM A
Upon completion, all material shall:. The minimum wall thickness at any point shall not be more than It is extremely ductile, with excellent strength at elevated temperatures.
It is less expensive than seamless or welded-and-drawn tubing. ASTM A Stainless steel tubes are finished in accordance with customer needs regarding dimensional and wall thickness specifications as well as heat treatment for more demanding applications. Yield Strength min ksi MPa.
Cut Length bIn. Ovality 2 x Tol. However, for thin-wall pipe the difference in extreme outside diameter readings ovality in any one cross-section shall not exceed 1.
Tubes not heat-treated to be stencilled: Tensile Strength min ksi MPa.
ASTM A269 / A269M Stainless Steel Seamless Tubes
Thin-wall pipe is defined as having a wall thickness of 3 percent or less of the outside diameter. Permissible Variations in Outside Diameter.
Ksi MPaMin. To compute safe working pressures, above burst pressures should be divided by your desired safety factor. The above diameter tolerances are not sufficient to provide for additional ovality except in thin-wall pipe and are applicable only to the mean of the extreme maximum and minimum outside diameter readings in any one cross-section.
The steel shall conform to the chemical composition requirements.
