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. A parallel item to add the grade to A484 is not required, because this new grade shares the heat treatment requirements for All austenitic grades except as listed below in the first line of Table 2 of A484/A484M. Finally, this item converts A276 from an inch-pound-only standard to a combined (dual-unit) standard.
