Yield Strength min, ksi MPa. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
ASTM A / AM – 11 Standard Specification for Seamless Stainless Steel Mechanical Tubing
Tolerances Hot Finished Round Table. 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. This specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed.
Largest Specified Outside Dimension, Inches. Permissible Variations in Cut Length in.
Also see Footnote B. 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 astk. Tubes to be used as hollow bar shall be furnished in round shape.
Specified Size, Outside Diameter, In. Small outside diameter tubes are defined as those under a 0. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. Permissible Variations in Cut Length, in. Tolerances — Diameter, Wall— Round Tubing. 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.
The values stated in a51 system are not exact equivalents; therefore, each system shall be used independently of the other.
Max Curvature in Total Lengths, in. Within the text, the SI units are shown in square brackets. Through a asttm and complete marking of packaging will create the conditions to avoid misuse, accidents, wrong delivery, mass and volume losses and customs penalties. The tubes shall be made by a seamless process and by either cold working or hot working as specified.
ASTM A511 / A511M, Stainless Steel Mechanical Seamless Tubes
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. An analysis of each heat of steel shall be made to determine the percentages of the elements specified. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
If determined by the dial indicator method, the values obtained will be approximately twice those determined by the straightedge feeler gage method. This specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed.
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 a51 thickness. C The columbium plus tantalum content shall be not less than ten times the carbon content and not more than 1. Wenzhou Sunrise Import and Export Co. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Link to Active This link will always route to the current Active version of the standard.
B For ovality values, the tolerance for average outside x511 at any one cross section does not exceed the outside diameter tolerance value for the applicable outside diameter.
ASTM A, ASTM A, ASTM A – Chicago Tube & Iron
Small outside diameter tubes are defined as those under a 0. Twist In 3 ft. Radii of Corners, max. The average of maximum and minimum outside diameter readings should fall within the outside diameter tolerances as shown in this table. We welcome small quantities. Subject to transport, duration and turnover can be wrapped in eg plastic jute fabric and is provided at the bundle ends and aa511 points with sheet metal bundled pipes. Specialty coatings, such as of PE, require padding to ensure that the protective layer is not damaged.
