Chemical Composition6.1 The material shall conform to the requirements, as tochemical composition specified in Table 2.6.2 If a product (check) analy

11、sis is performed by thepurchaser, the material shall conform to the product (check)analysis variations per Specification B751.7. Mechanical Properties and Other Requirements7.1 The tensile properties of the material at room tempera-ture shall conform to those shown in Table 1.7.2 Grain SizeAnnealed

12、Alloy UNS N08332 shall con-form to an average grain size of ASTM No. 5 or coarser.7.3 Annealing TemperatureAlloy UNS N08330 shall beannealed at 1900F (1040C) minimum. Alloy UNS N08332shall be annealed at 2050F (1120C) minimum.8. Keywords8.1 welded tube; N08330; N083321This specification is under the
