Within the text, the SI units are shown in square brackets. It axtm usually manufactured by hot working steel and then cold finishing the hot-worked tubing to produce the desired shape, dimensions and properties All austenitic tubes shall be furnished in the annealed condition.

The average of maximum and minimum outside diameter readings should fall within the outside diameter tolerances as shown in this table. Historical Version s – view previous versions of standard. Tensile Strength, min ksi MPa. Small outside diameter tubes are defined as those under a 0.

B For ovality values, the tolerance for average outside diameter at any one cross section does not exceed the outside diameter tolerance value for the applicable outside diameter. 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.

Outside Diameter, Tolerance,B in. Ratio of Wall Thickness to Outside Diameter. The steel may be cast in ingots or may be strand cast. Seamless steel tubing is a tubular product made without a welded seam. Elongation in 2 in. Tolerances — Diameter, Wall— Round Tubing. Within the text, the SI units are shown in square brackets. The straightness tolerance is 0.

OD over 5 in. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.

Specified Size, Outside Diameter, In. This abstract is a brief summary of the referenced standard.

ASTM A – 04 Standard Specification for Seamless Stainless Steel Mechanical Tubing

Subject to transport, duration and turnover can be wrapped in eg plastic jute fabric and is provided at asrm bundle ends and stop points with sheet metal bundled pipes. ASTM does not give any warranty express or implied or make a11 representation that the contents of this abstract are accurate, complete or up to date.

It is important to make sure that the strapping is very firm, so that the individual pipes can not move asrm each other and thereby suffer damage. C The columbium plus tantalum content shall be not less than ten times the carbon content and not more than 1.

A These tolerances apply to cut lengths up to and including 24 feet. An analysis of each heat of steel shall be made to determine the percentages of the elements specified.


ASTM A / AM – 11 Standard Specification for Seamless Stainless Steel Mechanical Tubing

The grades covered are listed in Table 1Table 2and Table 3. Specialty coatings, such as of PE, require padding to ensure that the protective layer is not damaged. For square or rectangular structural tubing with heavier walls, the radius of any outside corner astmm the section shall not exceed three times the specified wall thickness. For Wall Thickness, Given, in.

Wenzhou Sunrise Import and Export Co. A The usual procedure for measuring straightness is by means of a 3-ft 0. OD over 8 in.

If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. Small outside diameter tubes are defined as those under a 0. You should contrast clearly with the package, usually it is applied in black color. For sized over 5-in. Outside Diameter and Wall Thickness Tolerances.

Tolerances Hot Finished Round Table. SUNRISE is well-known as one of the leading astm a seamless stainless steel a5511 tubing manufacturers and suppliers in China for its quality products and excellent service.
