This abstract is a brief summary of the referenced standard.

Astmm that appear between these points shall be evaluated astj the basis of a straight line joining the two peak amplitudes.

Intricate parts are more likely to be available in alloys having a high rating. The materials for manufacture shall be rods, billets, or blanks of such purity and soundness as to be suitable for processing by hot pressing.

D, Robbins Ave. Soldering is rated as “excellent”, brazing is rated as “good”, oxyacetylene welding is “not recommended”, gas shielded arc welding is “not recommended”, coated metal arc welding is “not recommended”, spot welding is “not recommended”, seam welding is “not recommended”, and butt welding is rated as “fair”. It is the responsibility of the user of this standard to atsm appropriate safety, awtm, and environmental practices and determine the applicability of regulatory limitations prior to use.

F For n283 code application maximum iron content shall be 4. For tolerances applicable to heavier forgings, the manufacturers should be consulted. If approved by the purchaser, the forgings may be bundled or boxed and each bundle or box provided with a metal or oil-proof tag showing the above information.

C and C shall be furnished as: E This ast, copper plus silver plus sulfur plus phosphorus. A number in parentheses indicates the year of last reapproval.

The position and amplitude of the response from each notch shall be marked on the instrument screen or a transparent overlay, and these marks shall be used as the evaluation reference. For forgings exceeding lbs kgeach individual forging shall constitute a lot.

Material and Manufacture 6. C and C and speci? The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Work Item s – proposed revisions of this standard. The values shown represent the general opinion and are intended for information to enable the designer to better understand the forging characteristics of these various alloys.

A B Silver counting as copper. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Used for forgings requiring extensive machining, architectural hardware, fittings, mechanical components, specialty fasteners.

The recommended hot working temperature for this alloy is between and F. Originally approved in Note 1 — Nominal composition and relative forgeability ratings are given in Appendix X1. Combining values from the two systems may result in non-conformance with the standard. C and C shall be heat treated as speci? This alloy’s capacity for being hot formed is rated as “excellent”.

This standard does not purport to address all of the safety concerns, if any, associated with its use.
