Temper7.1 Drawn Tempers, HThe tempers of drawn tube shall be designated as light-drawn (H55), drawn (H58), and hard-drawn(H80) (see Table 2Tables 2 and 3). Light-drawn (bending) temper is used only when a tube of some stiffness b
29、ut yet capable ofbeing bent is needed. Drawn temper is for general purposes and is most commonly used where there is no specific requirementfor high strength on the one hand or for bending qualities on the other. Hard-drawn temper is used only where there is need fora tube as strong as is commercial
30、ly feasible for the sizes indicated. For any combination of diameter and wall thickness not coveredunder hard-drawn temper, the values given for drawn temper shall be used. Rectangular including square tubes shall normally besupplied only in drawn (general-purpose) temper. When there is a need for l
31、ight-drawn or hard-drawn tempers these are to besupplied as agreed upon between the manufacturer and the purchaser.7.2 Annealed Tempers, OThe tempers of annealed tube shall be designated as light anneal (O50) and soft anneal (O60) (Table3Tables 4 and 5).NOTE 1Tube of Copper Alloy UNS No. C23000, whe
32、n specified to meet the requirements of the ASME Boiler and Pressure Vessel Code, shall havein the annealed condition a minimum tensile strength of 40 ksi 275 MPa and a minimum yield strength of 12 ksi 80 MPa at 0.5 % extension underload, in which case the provisions for grain size and Rockwell hard
33、ness in 8.2 do not apply.8. Mechanical Properties8.1 Drawn TemperTube shall conform to the mechanical properties prescribed in Table 2Tables 2 and 3. Tension tests arerequired for tubes with a wall thickness under 0.020 in. 50 mm and for round tubes having an inside diameter under 516 in. 8.0mm and
34、for rectangular including square tubes having a major distance between inside parallel surfaces under 316 in. 5.0 mm.TABLE 1 Chemical RequirementsCopper Alloy UNS No. Composition,%Copper Lead Arsenic Tin Iron, max ZincC22000 89.091.0 0.05 max . . 0.05 remainderC23000 84.086.0 0.05 max . . 0.05 remai

38、on the Rockwell hardness tests cannot be reached, the tensile strength requirements of Table 2 shall be the basisfor acceptance or rejection.8.2 Annealed TemperTube shall conform to the grain size and Rockwell hardness limits prescribed in Table 3Tables 4 and5.9.
