Work Item s – proposed revisions of this standard. The capacity for cold working this alloy is rated as “poor”. Link to Active This link will always route to asgm current Active version of the standard.

ASTM B283 Grade C37700

Alternatively, samples may be taken from separately forged test bars of the same heat as the forgings in the lot provided the wall thickness and amount of working for the test bar are equivalent to those for the forgings.

Copper-nickel alloys C and C are intended for welded applications with seawater exposure. Last previous edition approved in as B — B — 06 Standard Speci? A superscript epsilon e indicates an editorial change since the last revision or reapproval.

C and C shall be heat treated as speci? NOTE 3—Due to the discontinuous nature of the processing of castings into wrought products, it is not always practical to identify speci?

For contact testing, the search unit shall be? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. F For boiler code application maximum iron content shall be 4. Indications that appear between these points shall be evaluated on the basis of a straight line joining the two peak amplitudes.

Combining values from the two systems may result in non-conformance with the standard. 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. Sampling—The lot size, portion size, and selection of sample pieces shall be as follows: The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.

Intricate parts are more likely to be available in alloys having a high rating. By agreement between manufacturer and purchaser, limits may be established and analysis required for unnamed elements.

For forgings exceeding lbs kgeach individual forging shall constitute a lot. 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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

The materials for manufacture shall be rods, billets, or blanks of such purity and soundness as to be suitable for processing by hot pressing. A number in parentheses indicates the year of last reapproval. This standard does not purport to address all of the safety concerns, if any, associated with its use.

For tolerances applicable to heavier forgings, the manufacturers should be consulted. 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.

This abstract is a brief summary of the referenced standard. H Carbon shall be 0. Includes oxygen-free or deoxidized grades with deoxidizers such as phosphorus, boron, lithium, or others in amount agreed upon. Therefore, the data in Table X3. The values stated in each system may not be bb283 equivalents; therefore, each system shall be used independently of the other. 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.

Astn 1—Nominal composition and relative forgeability ratings are given in Appendix X1. The hot forgeability rating of this alloy is Material and Manufacture 6. Tensile tests shall be performed on each forging over lbs kg. D, Robbins Ave. Copper-nickel alloys C and C are intended for welded applications with seawater exposure. 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”.
