32、.85to1.20.A249/A249M 1433. Ordering Information3.1 It is the responsibility of the purchaser to specify allrequirements that are necessary for material ordered under thisspecification. Such requirements may include, but are notlimited to, the following:3.1.1 Quantity (feet, metres, or number of leng
33、ths),3.1.2 Name of material welded tubes (WLD) or heavily coldworked tubes (HCW),3.1.3 Grade (Table 1),3.1.4 Size (outside diameter and nominal wall thickness),3.1.5 Length (specific or random),3.1.6 Optional requirements (13.6),3.1.7 Test report required (see Certification Section ofSpecification A
34、1016/A1016M),3.1.8 Specification designation, and3.1.9 Special requirements and any supplementary require-ments selected.4. General Requirements4.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A1016/A1016M, unless ot
35、herwise providedherein.5. Manufacture5.1 The welded (WLD) tubes shall be made from flat-rolledsteel by an automatic welding process with no addition of fillermetal.5.1.1 Subsequent to welding and prior to final heattreatment, the tubes shall be cold worked either in both weldand base metal or in wel
36、d metal only. The method of coldworking may be specified by the purchaser. When cold drawn,the purchaser may specify the minimum amount of reduction incross-sectional area or wall thickness, or both.5.1.2 Heavily cold worked (HCW) tubes shall be made byapplying cold working of not less than 35 % red
37、uction in bothwall and weld to a welded tube prior to the final anneal. Nofiller metal shall be used in the making of the weld. Prior tocold working, the weld shall be 100 % radiographically in-spected in accordance with the requirements of ASME Boilerand Pressure Vessel Code, Section VIII, Division
38、 1, latestrevision, Paragraph UW 51.6. Heat Treatment6.1 All material shall be furnished in the heat-treatedcondition in accordance with the requirements of Table 2.6.2 A solution annealing temperature above 1950 F 1065C may impair the resistance to intergranular corrosion aftersubsequent exposure t
39、o sensitizing conditions in TP309HCb,TP310HCb, TP321, TP321H, TP347, TP347H, TP348, andTP348H. When specified by the purchaser, a lower temperaturestabilization or re-solution anneal shall be used subsequent tothe initial high temperature solution anneal (see SupplementaryRequirement S4).7. Chemical
40、 Composition7.1 The heat analysis shall conform to the requirements asto chemical composition given in Table 1.8. Product Analysis8.1 An analysis of either one length of flat-rolled stock orone tube shall be made for each heat. The chemical composi-tion thus determined shall conform to the requireme
41、nts given inSection 7.8.2 A product analysis tolerance of Table A1.1 in Specifi-cation A480/A480M shall apply. The product analysis toler-ance is not applicable to the carbon content for material with aspecified maximum carbon of 0.04 % or less.8.3 If the original test for product analysis fails, re
42、tests oftwo additional lengths of flat-rolled stock or tubes shall bemade. Both retests for the elements in question shall meet therequirements of the specification; otherwise all remainingmaterial in the heat or lot (See Note 1) shall be rejected or, atthe option of the producer, each length of fla
43、t-rolled stock ortube may be individually tested for acceptance. Lengths offlat-rolled stock or tubes that do not meet the requirements ofthe specification shall be rejected.NOTE 1For flattening and flange requirements, the term lot applies toall tubes prior to cutting of the same nominal size and w
44、all thicknesswhich are produced from the same heat of steel. When final heat treatmentis in a batch-type furnace, a lot shall include only those tubes of the samesize and from the same heat which are heat treated in the same furnacecharge. When the final heat treatment is in a continuous furnace, th
45、enumber of tubes of the same size and from the same heat in a lot shall bedetermined from the size of the tubes as prescribed in Table 3.NOTE 2For tension and hardness test requirements, the term lotapplies to all tubes prior to cutting, of the same nominal diameter and wallthickness which are produ
46、ced from the same heat of steel. When final heattreatment is in a batch-type furnace, a lot shall include only those tubes ofthe same size and the same heat which are heat treated in the same furnacecharge. When the final heat treatment is in a continuous furnace, a lot shallinclude all tubes of the
47、 same size and heat, annealed in the same furnaceat the same temperature, time at heat, and furnace speed.9. Tensile Requirements9.1 The material shall conform to the tensile propertiesprescribed in Table 4.10. Hardness Requirements10.1 The tubes shall have a Rockwell hardness number notexceeding th
48、e values specified in Table 4.11. Reverse-Bend Test Requirement11.1 A section 4 in. 100 mm minimum in length shall besplit longitudinally 90 on each side of the weld. The sampleshall then be opened and bent around a mandrel with amaximum thickness of four times the wall thickness, with themandrel parallel to the weld and against the original outsidesurface of the tube. The weld shall be at the point of maximumbend. There shall be no evidence of cracks, or of overlapsresulting from the reduction in thickness of the weld areas bycold working. When the geometry or s
