Nominal composition and relative forgeability ratings are given in Appendix X1.
Alternatively, samples may be taken from separately forged test bars of the same heat as the forgings in the lot provided the wall asrm and amount of working for the test bar are equivalent to those for the forgings. D Other deoxidizers may be used as agreed upon, in which case phosphorus need not be present.
For contact testing, the search unit shall be? This standard does not purport to address all of the safety concerns, if any, associated with its use.

They are given merely to indicate to the purchaser the various forging types and some dimensional toler- ances used on commercially designed hot-pressed forgings up to 2 lbs 0. Intricate parts are more likely to be available in alloys having a high rating.
In the event of disagreement on the degree of back re? E This includes copper plus silver plus sulfur plus phosphorus. C This includes copper plus silver plus tellurium. Originally approved in Work Item s – proposed revisions of this standard. It is astj 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. The capacity for cold working this alloy is rated as “poor”.
