General Requirements4.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A1016/A1016M, unless other
28、wise providedherein.5. Manufacture5.1 The tubes shall be made by the seamless or weldedprocess.5.2 At the manufacturers option, tubing may be furnishedeither hot finished or cold finished.6. Heat Treatment6.1 All material shall be furnished in the heat-treatedcondition. Except as provided in 6.2, th
29、e heat-treatment pro-cedure shall, except for S31254 and S32654 (see 6.3), S34565(see 6.4), N08367 (see 6.8), N08904 (see 6.5) and N08926 (see6.7), consist of heating the material to a minimum temperatureof 1900 F (1040 C) and quenching in water or rapidlycooling by other means. Alternatively, for s
30、eamless tubes,immediately following hot forming while the temperature ofthe tubes is not less than the specified minimum solutiontreatment temperature, tubes may be individually quenched inwater or rapidly cooled by other means.6.2 Controlled structural or special service characteristicsshall be spe
31、cified as a guide for the most suitable heattreatment. If the final heat treatment is at a temperature under1900 F and is so specified on the order, each tube shall bestenciled with the final heat treatment temperature in degreesFahrenheit after the suffix “HT”.6.3 S31254 and S32654 shall be heat-tr
32、eated to a minimumtemperature of 2100 F (1150 C) followed by quenching inwater or rapidly cooling by other means.6.4 S34565 shall be heat-treated in the range 2050 F (1120C) to 2140 F (1170 C) followed by quenching in water orrapidly cooling by other means.6.5 N08904 shall be heat treated to a minim
33、um temperatureof 2000 F (1100 C) followed by quenching in water orrapidly cooling by other means.6.6 A solution annealing temperature above 1950 F (1065C) may impair the resistance to intergranular corrosion aftersubsequent exposure to sensitizing conditions in TP321,TP347, and TP348. When specified
34、 by the purchaser, a lowertemperature stabilization or re-solution anneal shall be usedsubsequent to the initial high temperature solution anneal (seeSupplementary Requirement S3).6.7 N08926 shall be heat-treated to a minimum temperatureof 2010 F (1100 C) followed by quenching in water orrapidly coo
35、ling by other means.6.8 UNS N08367 should be solution annealed from 2025 F(1107 C) minimum followed by rapid quenching.6.9 Solution annealing of S35045 shall consist of heatingthe material to a temperature of 2000 F (1093 C) minimumfor an appropriate time, followed by cooling in still air or at afas
36、ter rate.6.10 S31727 and S32053 shall be solution annealed in therange 1975 to 2155 F (1080 to 1180 C) followed byquenching in water or rapidly cooling by other means.7. Chemical Composition7.1 The steel shall conform to the requirements as tochemical composition as prescribed in Table 1.8. Product
37、Analysis8.1 An analysis of either one billet or one length offlat-rolled stock or one tube shall be made from each heat. Thechemical composition thus determined shall conform to therequirements specified.8.2 A product analysis tolerance of Table number A1.1 inSpecification A480/A480M shall apply. Th
38、e product analysistolerance is not applicable to the carbon content for materialwith a specified maximum carbon of .04 % or less.8.3 If the original test for product analysis fails, retests oftwo additional billets, lengths of flat-rolled stock, or tubes shallbe made. Both retests for the elements i
39、n question shall meetthe requirements of the specification; otherwise all remainingmaterial in the heat or lot shall be rejected or, at the option ofthe producer, each billet, length of flat-rolled stock, or tubemay be individually tested for acceptance. Billets, lengths offlat-rolled stock, or tube
40、s which do not meet the requirementsof the specification shall be rejected.9. Mechanical Tests Required9.1 Flaring Test (Seamless Tubes) One test shall be madeon specimens from one end of one tube from each lot (Note 2)of finished tubes.NOTE 2The term lot applies to all tubes prior to cutting to len
41、gth ofthe same nominal size and wall thickness which are produced from thesame heat of steel. When final heat treatment is in a batch-type furnace, aheat-treatment lot shall include only those tubes of the same size and fromthe same heat which are heat treated in the same furnace charge. When thefin
42、al heat treatment is in a continuous furnace or when the heat-treatedcondition is obtained directly by quenching after hot forming, the numberof tubes of the same size and from the same heat in a heat-treatment lotshall be determined from the size of the tubes as prescribed in Table 2.9.2 Flange Tes
