ASTM B591-98a pdf free.Standard Specification for Copper-Zinc-Tin and Copper-Zinc-Tin-Iron-Nickel Alloys Plate, Sheet, Strip, and Rolled Bar.
Contracts or purchase orders for product under thisspecification should include the following information:ASTM designation and year of issue (for example,B591-XX);Copper Alloy UNS No. Designation (for example,C42500);Temper (see Section 8);Dimensions， that is, thickness，width,length,and soforth (see Section 12);Form,that is, plate, sheet,strip, or rolled bar;How furnished, that is, rolls, specific or stock lengths,with or without ends;
Quantity, that is, total weight each form,temper,andsize; and When material is purchased for agencies of the U.S.Government the requirements of Section 11 shall apply.The following options are available under this specifi-cation and should be specified in the contract or purchase orderwhen required:Type of edge,that is，slit，sheared,sawed,squarecorners,round corners, rounded edges, or full rounded edges,andWidth and straightness tolerances (see Section 12).The material of manufacture shall be Copper AlloyUNS No. C40500,C41100,C41300,C41500，C42200,C42000，C43300，C43400，C40810,C40850,C40860，orC42520 as specified in the ordering information.In the event that heat identification or traceability isrequired, the purchaser shall specify the details desired.The material shall conform to the chemical composi-tional requirements specified in Table 1 for the copper alloyUNS No. designation specified in the ordering information.7.1.1 These composition limits do not preclude the possiblepresence of other unnamed elements. Limits may be estab-iished and analysis required for unnamed elements by agree-ment between manufacturer or supplier and the purchaser.7.2Zinc，given as the“Remainder,” is the difference be-tween the sum of the results for all elements determined and100 %.
Copper may be determined by difference; however,when so determined, the results must conform to the require-ments of Table 1.
When all elements specified in Table 1 for the desig-nated alloy are determined,the sum of results shall equal atleast 99.7 %.
As Hot Rolled (M20) Material—This standard temper ofsheet and plate produced by hot rolling, where applicable, isshown in Table 2.(See Table 3 for Sl equivalents.)H (Rolled Material)—The standard tempers of rolledmaterials are as designated in Table 2 with the prefix“H.”Special tempers not listed in this specification are subject toagreement between the manufacturer and the purchaser.
Annealed Material—The standard tempers of annealedmaterial are as designated in Table 4 in the column entitled“Nominal Grain Size.”Special tempers not listed in thisspecification are subject to agreement between the manufac-turer and the purchaser.Temper designations are defined in Practice B 601.ASTM B591 pdf download.
