Your comments will receive careful consideration at a meeting of the responsible technical committee, which sstm may attend. When agreed upon between the manufacturer and the purchaser, forgings weighing less than lb kg each rough-machined weight may be tested in lots; the number of forgings to make up a lot shall be by mutual agreement.

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. This specification covers normalized and tempered carbon steel, and liquid quenched and tempered alloy steel forgings for pinions, gears, and shafts for reduction gears.

ASTM A291 Grade 5

The purchaser may indicate the desired location of such identi? A — 03 Standard Speci? When vacuum carbon deoxidation is used, silicon maximum shall be 0.

Hardness tests shall be performed at the quarter-face width of the tooth portion diameter.

It’s easy to join and it’s free. 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.

Historical Version s – view previous versions of standard. Prior to heat treatment for mechanical properties testingsteel materials may undergo machining and boring, after which specimens shall be stress relieved. Originally approved in Also, one has the option to make the more easily replaced part of an assembly somewhat softer to save on eventual maintainance.

The Eng-Tips staff will check this out and take appropriate action. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Last previous edition approved in as A — Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Current edition approved Apr.

So, first design the small diameter Pinions, Gears and Shafts per A, then choose a matching alloy in Table 1 of A for the large diameter ring gear. A number in parentheses indicates the year of last reapproval.

This abstract is a brief summary of the referenced standard. The hardness testing is a validation of heat treatment. Combining values from the two systems may result in non-conformance with the standard. Work Item s – proposed revisions of this standard. 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. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.


Minimum tempering temperatures shall be as follows: Promoting, selling, recruiting, coursework and thesis posting is forbidden.

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 On each forging under 8 in. Specimens shall also conform to chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, copper, and aluminum. These specifications were developed for optimum gear performance. There is 2a91 estimating of mechanical properties.
