C and C shall be furnished as: Combining values from the two systems may result in non-conformance with the standard. The product also shall be inspected with a longitudinal wave test from the external circumferential and end surfaces.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Active view current version of standard. This specification establishes the requirements for copper and copper die forgings produced by hot pressing asrm. 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.
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”. 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.
Notch length shall not exceed 1 aastm.
C Up to 11? Last previous xstm approved in as B — This standard does not purport to address all of the safety concerns, if any, associated with its use. C and C and speci? Note 1—Nominal composition and relative forgeability ratings are given in Appendix X1.

C and C shall depend only on tensile strength. B — 06 Standard Speci? C, C, C, C, Cthe sum of results shall be Intricate parts are more likely to be available in alloys having a high rating. Modulus of Elasticity Tension. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Flat Rolled Products by 2 distributors but is also available to a lesser extent in Bar Products.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
G Iron content shall not exceed nickel content. Copper-nickel alloys C and C are intended for welded axtm with seawater exposure.
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. The following copper and copper alloys are included: The following copper and copper alloys are included: The machinability rating of this alloy is Copper-nickel alloys C and C are intended for welded applications with seawater exposure.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
ASTM B283 Grade C37700
F For boiler code application maximum iron content shall be 4. NOTE 3—Due to the discontinuous nature of the processing of castings into wrought products, it is not always practical to identify speci?
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Tensile tests shall be performed on each forging over lbs kg. This alloy’s capacity for being hot formed is rated as “excellent”. A number in parentheses indicates the year of last reapproval. Historical Version s – view previous versions of standard. Therefore, the data in Table X3. For tolerances applicable to heavier forgings, the manufacturers should be consulted.
