Specified Size, Outside Diameter, in. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Small outside diameter tubes are defined as those under a 0. B The titanium content shall be not less than five times the carbon content and asym more than 0.
E These tolerances apply to cut lengths up to and including 24 feet. Yield Strength min, ksi MPa. An analysis of each heat of steel shall be made to determine the percentages of the elements specified. Specified Size, Outside Diameter, In. If determined by the dial indicator method, the values obtained will be approximately twice those determined by the straightedge feeler gage method. Elongation in 2 in. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Largest Specified Outside Dimension, Inches. OD over 8 in. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members. Nominal Pipe Size Inches.
Where ellipses … appear in this table, there is no requirement and analysis for the element need not be determined or reported. The average of maximum and minimum outside diameter readings should fall within the outside diameter tolerances as shown in this table. Outside Diameter and Atm Thickness Tolerances.
We welcome small quantities. This specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed. 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. Within the text, the SI units are shown in square brackets.
Twist In 3 ft. Radii atsm Corners, max.

The steel may be cast in ingots or may be strand cast. Tubes to be used as hollow bar shall be furnished in round shape. For Wall Thickness, Given, in. Stainless Steel Seamless Tubes: Ovality is the difference between maximum and minimum outside ast measured at any one cross section. For sizes up to and including 5-in. It is important to make sure that the strapping is very firm, so that the individual pipes can not move against each other and thereby suffer damage. Max Curvature in Total Lengths, in.
Wenzhou Sunrise Import and Export Co.
OD over 5 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. Tolerances — Diameter, Wall— Round Tubing. We warmly welcome you to buy the quality and durable steel products from our factory.
ASTM A – 04 Standard Specification for Seamless Stainless Steel Mechanical Tubing
Historical Version s – view previous versions of standard. Outside Diameter, Tolerance,B in. 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. This specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or zstm strength is needed.
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. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to astj its use and application. The straightness tolerance is 0. A These tolerances apply to cut lengths up to and including 24 feet.

Therefore, the wall thickness can vary 15 a51 over and under that specified, and the inside diameter is governed by both the outside diameter and wall thickness tolerances. Permissible Variations in Cut Length, in. Small outside diameter tubes are defined as those under a 0. For sized over 5-in. Tolerances Hot Finished Round Table. You should contrast clearly with the package, usually it is applied in black color.
SUNRISE aa511 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. This abstract is a brief summary of the referenced standard.
A For small diameter or thin wall tubing or both, where many drawing passes are required, a maximum of 0. 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.
