Now note the correlation between chemistries in Table 1 of each spec. The purchaser may indicate the desired location of such identi?

Hardness tests shall be performed at the quarter-face width of the tooth portion diameter. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. But, the ASTM committee asfm some thinking in order to handle the exceptional cases. This specification covers normalized and tempered carbon steel, and liquid quenched and tempered alloy steel forgings for pinions, gears, and shafts for reduction gears.

Dimensions and Tolerance 9. There is no estimating of mechanical properties. ASTM A establishes either a diameter or thickness range for the mechanical properties on table 3 for the different classes of steel. Join your peers on the Internet’s largest technical engineering professional adtm.

Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.


When impact tests are speci? 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. Am I correct if I say that the only difference between the 2 Stds.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM a2991 the above address or at phonefaxor service astm. Also, one has the option to make the more easily replaced part of an assembly somewhat softer to save on eventual maintainance.

Brinell Hardness Number Range to to Grade Class Tensile Strength, min psi 85 80 95 95 95 MPa Charpy V-notch 3, 3A C, D Link to Active This link will always route to the current Active version of the standard. Defense manufacturing is all about project manufacturing and project accounting.

And if the above-mentioned question is truewhat would be the difference in designing a forging based on the technical attributes of either one or asttm other? Work Item s – proposed revisions of this standard.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Grade 1 shall be air cooled while Grades 2 through 9 shall be liquid quenched. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Does it mean that regardless the thickness of my forgingI can only estimate mechanical properties through the HB figures?

The forgings shall be heated to a suitable temperature for a sufficient length of time for austenitization and shall be suitably cooled to bring about complete transformation. Combining values from the two systems may result in non-conformance with the standard.


Welding technique is of fundamental importance and it is presupposed that welding procedure and inspection shall be in accordance with approved methods for the class of material used. When vacuum carbon deoxidation is used, silicon maximum shall be 0.

Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. Specimens shall also conform to chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, copper, and aluminum.

If you feel that your comments have aa291 received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

ASTM A291 Grade 5

Originally approved in The hardness testing is a validation of heat treatment. Welding technique is of fundamental importance and it is presupposed that welding procedure and inspection shall be in accordance with approved methods for the class of material used. I would partially agree with kenvlachbut have a ME in gear design double check. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Prior to heat treatment for mechanical properties testingsteel materials may undergo machining and boring, after which specimens shall be stress relieved.
