15、, PO Box C700, West Conshohocken, PA 19428-2959. United States17. Material and Manufacture7.1 Tube shall be made from flat-rolled alloy by an auto-matic welding process with no addition of filler metal. Subse-quent to welding and prior to final solution treatment Class 1and Class 2 material shall be
16、 cold worked either in both weldand base metal or in weld metal only.NOTE 2The recommended heat treatment shall consist of heating to aminimum temperature of 2025F (1105C) for Type N08367 and quench-ing in water or rapidly cooling by other means.7.2 Tube shall be furnished with oxide removed. Whenso
17、lution treatment is performed in a protective atmospheredescaling is not necessary.8. Chemical Composition8.1 The material shall conform to the requirements as tochemical composition prescribed in Table 1. One test isrequired for each lot as defined in Specification B751.8.2 If a product (check) ana
18、lysis is performed by thepurchaser, the material shall conform to the product (check)analysis variations specified in Specification B751.9. Mechanical Properties and Other Requirements9.1 Mechanical PropertiesThe material shall conform tothe mechanical properties prescribed in Table 2. One test isre
19、quired for each lot as defined in Specification B751.9.2 Flattening Test Requirements:9.2.1 One flattening test per lot shall be performed inaccordance with Specification B751.9.3 Flange Test Requirements:9.3.1 Flange test specimens shall show no cracking or flaws.9.3.2 For tube less than 0.093 in.
20、(2.36 mm) in insidediameter and tube having a wall thickness equal to or greaterthan the inside diameter, the flange test shall not be required.9.4 Reverse-Bend Requirements:9.4.1 One reverse-bend test as defined in SpecificationA1016/A1016M shall be performed on each lot of tubing.9.4.2 Reverse-ben
21、d test specimens shall show no evidenceof cracks or lack of penetration in the weld, or of overlapsresulting from the reduction in thickness of the weld areas bycold working.9.4.3 The reverse-bend test is not applicable when thespecified wall is 10 % or more of the specified outsidediameter, or the
22、wall thickness is 0.134 in. (3.4 mm) or greater,or the outside diameter size is less than 0.375 in. (9.5 mm).Under these conditions the reverse flattening test of Specifica-tion A1016/A1016M shall apply.9.4.4 The lot definition for the reverse-bend test shall be1500 ft (450 m) of finished tubing.9.5
23、 Nondestructive Test Requirements:9.5.1 Tube shall be subjected to a pressure test or nonde-structive electric test in accordance with Specification B751.10.
