C23000, C44300,C44400, C44500, and C68700 shall be furnished in theannealed temper or the stress relieved condition as specified inthe purchase order unless otherwise agreed upon between thepurchaser and the manufacturer or supplier.8.4 Tubes
37、 of Copper Alloy UNS Nos. C12200, C19400,C70400, C70600, C70620, C71000, C71500, C71520,C71640, and C72200 are normally supplied in the temperspecified in the purchase order without stress relief treatment.NOTE 1Some tubes, when subjected to aggressive environments, maybe subject to stress-corrosion
38、 cracking failure because of the residualtensile stresses developed in straightening. For such applications, it issuggested that tubes of Copper Alloy UNS Nos. C23000, C44300,C44400, C44500, and C68700 be subjected to a stress relieving thermaltreatment subsequent to straightening. If required, this
39、 must be specifiedon the purchase order or contract. Tolerances for roundness and length,and the condition of straightness, for tube so ordered, shall be to therequirements agreed upon between the manufacturer and the purchaser.9. Grain Size for Annealed Tempers9.1 Samples of annealed temper tubes s
40、hall be examined ata magnification of 75 diameters. The grain size shall bedetermined in the wall beneath the internal enhancement.While there is not grain size range, the microstructure shallshow complete recrystallization and the weld zone shall have astructure typical of hot-forged welds.TABLE 1
