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.

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.

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.
