ASTM A, ASTM A, ASTM A – Chicago Tube & Iron

For sized over 5-in. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. An analysis of each heat of steel shall be made to determine the percentages of the elements specified.

Specified Size, Outside Diameter, in.

Permissible Variations in Cut Length in. This specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed. OD over 5 in.

For sizes up to and including 5-in.

Specialty coatings, such as of PE, require padding to ensure that the protective q511 is not damaged. A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases fluidsslurries, powders, masses of small solids.

If secondary melting processes are employed, the heat analysis asttm be obtained from one remelted ingot or the product of one remelted ingot of each primary melt.

You should contrast clearly with the package, usually it is applied in black color. It is 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. Permissible Variations in Cut Length, in.


Elongation q511 2 in. 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. Twist In 3 ft. Therefore, the wall thickness can vary 15 percent over and under that specified, and the inside diameter is governed by both the outside diameter and wall thickness tolerances.

For Wall Thickness, Given, in. Nominal Pipe Size Inches. Link to Active This link will always route to the current Active version of the standard. Wenzhou Sunrise Import and Export Co.

ASTM A511/A511M Standard Specification for Mechanical

Tolerances — Diameter, Wall— Round Tubing. Tubes to be used as hollow bar shall be furnished in round shape. Ratio of Wall Thickness to Outside Diameter.

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

Max Curvature in Total Lengths, in. SUNRISE is well-known as one of the leading astm a seamless stainless steel mechanical tubing manufacturers and suppliers in China for its quality products and excellent service. Subject to transport, duration and turnover can be wrapped in eg plastic jute fabric and is provided at the bundle ends and stop points with sheet metal bundled pipes.

Where ellipses … appear in this table, there is no requirement and analysis for the element need not be determined or reported. For square or rectangular structural tubing with heavier walls, the radius of any outside corner of the section shall not exceed three times the specified wall thickness.


Radii of Corners, max. Ovality is the difference between maximum and minimum outside diameters measured at any one cross section. Tensile Strength, min ksi MPa. Historical Version s – view previous versions of standard. C The columbium plus tantalum content shall be not less than ten times the carbon content and not more than 1.

ASTM A511 Grade MT316

B The titanium content shall be not less than five times the carbon content and not more than 0. The grades covered are listed in Table 1 and Table 2. Outside Diameter and Wall Thickness Tolerances. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. A These tolerances apply to cut lengths up to and including 24 ft 7. The steel may be cast in ingots or may be strand cast. The grades covered are listed in Table 1Table xstmand Table 3.

This abstract is asfm brief summary of the referenced standard.

Through a correct and complete marking of packaging will create the conditions to avoid misuse, accidents, wrong delivery, mass and volume losses and customs penalties. B For ovality values, the tolerance for average outside diameter at any one cross section does not exceed the outside diameter s511 value for the applicable outside diameter. If determined by the dial indicator method, the values obtained will be approximately twice those determined by the straightedge feeler gage method.
