ASTM B584-00 pdf free.Standard Specification for Copper Alloy Sand Castings for General Applications.
Copper alloy UNS Nos.C94700 and C96800 may besupplied in the heat treated condition to obtain the highermechanical properties shown in Table 2.Suggested heattreatments for these alloys are given in Table 3.Actual practicemay vary by manufacturer.
Separately cast test bar coupons representing castingsmade in copper alloy UNS Nos.C94700HT and C96800HTshall be heat treated with the castings.
The castings shall conform to the compositional require-ments for named elements as shown in Table 4 for the copperalloy UNS numbers specified in the purchase order.These specification limits do not preclude the presenceof other elements. Limits may be established and analysisrequired for unnamed elements agreed upon between manu-facturer or supplier and purchaser. Copper or zinc, when zincis 20 % or greater，may be given as remainder and may betaken as the difference between the sum of all elementsanalyzed and 100 %.When all named elements in Table 4 areanalyzed, their sum shall be as specified in Table 5.It is recognized that residual elements may be present incast copper alloys. Analysis shall be made for residual ele-ments only when specified in the purchase order. Mechanical properties shall be determined from sepa-rately cast test bar castings,and shall meet the requirementsshown in Table 2.The castings shall not be weld repaired without approvalof the purchaser (5.2.3).The castings shall not be impregnated without approvalof the purchaser (5.2.3).When specified in the purchase order to meet ASMEBoiler and Pressure Vessel Code requirements，castings incopper alloy UNS Nos.C92200，C93700，and C97600 shallcomply with the following:
Certification requirements of Specification B 824.10.1.2 Foundry test report requirements of SpecificationB824.
Castings shall be marked with the manufacturer’sname, the copper alloy UNS number， and the casting qualityfactor. In addition，heat numbers or serial numbers that aretraceable to heat numbers shall be marked on all pressure-containing castings individually weighing 50 lbs (22.7 kg) ormore. Pressure-containing castings weighing less than 50 lbs(22.7 kg) shall be marked with either the heat number or aserial number that will identify the casting as to the month inwhich it was poured. Marking shall be in such a position as tonot impair the usefulness of the casting.ASTM B584 pdf download.
