Chemical Composition6.1 The material shall conform to the chemical compositionrequirements specified in Table 1.6.2 These compositio
17、n limits do not preclude the presenceof other elements. Limits may be established and analysisrequired for unnamed elements by agreement between themanufacturer and purchaser.6.3 For Alloy UNS C69100 where zinc is listed as “remain-der,” zinc is the difference between the sum of results of allelemen

22、strength.9.2 Rockwell HardnessThe approximate hardness valuefor alloy UNS C69100 lies within the range 69 to 76 RockwellB, being for general information and assistance in testing, andshall not be used as a basis for product rejection.NOTE 2The Rockwell hardness test offers a quick and convenientmeth
23、od of checking for general conformity to the specification require-ments for temper, tensile strength and grain size.10. Other Requirements10.1 Nondestructive Testing:10.1.1 Pipe or tube must be tested in the final heat-treatedcondition as supplied to the purchaser unless otherwise agreedupon betwee
24、n the manufacturer and purchaser. Unless other-wise specified, the manufacturer shall have the option oftesting the pipe or tube by one of the following tests:10.1.1.1 Eddy-Current TestEach tube or pipe in standardsizes18 in. (3.18 mm) up to and including 212 in. (63.5 mm)regular and extra strong, s
25、hall be subject to an eddy-current testfollowing the procedures of Practice E 243 and using an endeffect suppression device. The pipe or tube shall be passedthrough the eddy-current testing unit to provide information onthe suitability of each piece for the intended application.10.1.1.2 Notch-depth
26、standards, rounded to the nearest0.001 in. (0.025 mm), shall be 10 % of the nominal wallthickness. Notch-depth tolerances shall be 60.0005 in. (0.013mm). Alternatively, when a manufacturer uses speed-insensitive equipment that can select a maximum unbalancesignal, such a signal of 0.3 % may be used.
27、10.1.1.3 Pipes or tubes that do not activate the signalingdevice of the eddy-current tester shall be considered asconforming to the requirements of this test. Lengths withdiscontinuities indicated by the tester may, at the option of themanufacturer, be reexamined or retested to determine whetherthe
28、discontinuity is cause for rejection. Signals that are foundto have been caused by minor mechanical damage, soil, ormoisture shall not be cause for rejection provided the pipe ortube dimensions are still within the prescribed limits and thepipe or tube is suitable for its intended application.10.1.2
29、 Hydrostatic TestEach length shall stand, withoutshowing evidence of leakage, an internal hydrostatic pressuresufficient to subject the material to a fiber stress of 7000 psi (48MPa) determined by the following equation for thin hollowcylinders under internal pressure. The pipe or tube need not bete
