Active Standard: A269 - 13
A user has requested addition of a new grade, 317CU, of a nominal composition of 18 Cr- 16 Ni- 4.5 Cu- 3.5 Mo- N. The grade designation, 317CU, is temporary, and will be replaced by a UNS Number when one is issued. Request letters from a user and a data package supporting the request have been provided. The letter and the required data are appended to the ballot item. This action also adds N08925 to this specification. This alloy, now considered a ferrous alloy, had been moved from a B specification to A213 and A312 some time ago, and should have been added to A269 at that time. This grade does not require either a request letter or a data package, since it is already listed in other A01 and B02.07 specifications. Finally, this action converts this specification to a combined (dual-unit) standard.
