General R
31、equirements4.1 Material furnished under this specification shall conform to the applicable requirements of the current edition ofSpecification A1016/A1016M, unless otherwise provided herein.5. Manufacture5.1 The tubes shall be made by the seamless or welded process.5.2 At the manufacturers option, t
32、ubing may be furnished either hot finished or cold finished.6. Heat Treatment6.1 All material shall be furnished in the heat-treated condition. Except as provided in 6.2, the heat-treatment procedure shall,except for S31254 and S32654 (see 6.3), S34565 (see 6.4), N08367 (see 6.8), N08904 (see 6.5) a
33、nd N08926 (see 6.7), consist ofheating the material to a minimum temperature of 1900 F (1040 C) and quenching in water or rapidly cooling by other means.Alternatively, for seamless tubes, immediately following hot forming while the temperature of the tubes is not less than thespecified minimum solut
34、ion treatment temperature, tubes may be individually quenched in water or rapidly cooled by other means.6.2 Controlled structural or special service characteristics shall be specified as a guide for the most suitable heat treatment. Ifthe final heat treatment is at a temperature under 1900 F and is
35、so specified on the order, each tube shall be stenciled with thefinal heat treatment temperature in degrees Fahrenheit after the suffix “HT”.6.3 S31254 and S32654 shall be heat-treated to a minimum temperature of 2100 F (1150 C) followed by quenching in wateror rapidly cooling by other means.6.4 S34
36、565 shall be heat-treated in the range 2050 F (1120 C) to 2140 F (1170 C) followed by quenching in water or rapidlycooling by other means.6.5 N08904 shall be heat treated to a minimum temperature of 2000 F (1100 C) followed by quenching in water or rapidlycooling by other means.6.6 A solution anneal
37、ing temperature above 1950 F (1065 C) may impair the resistance to intergranular corrosion aftersubsequent exposure to sensitizing conditions in TP321, TP347, and TP348. When specified by the purchaser, a lower temperaturestabilization or re-solution anneal shall be used subsequent to the initial hi
38、gh temperature solution anneal (see SupplementaryRequirement S3).6.7 N08926 shall be heat-treated to a minimum temperature of 2010 F (1100 C) followed by quenching in water or rapidlycooling by other means.6.8 UNS N08367 should be solution annealed from 2025 F (1107 C) minimum followed by rapid quen
39、ching.6.9 Solution annealing of S35045 shall consist of heating the material to a temperature of 2000 F (1093 C) minimum for anappropriate time, followed by cooling in still air or at a faster rate.6.10 S31727 and S32053 shall be solution annealed in the range 1975 to 2155 F (1080 to 1180 C) followe

Product Analysis8.1 An analysis of either one billet or one length of flat-rolled stock or one tube shall be made fro
41、m each heat. The chemicalcomposition thus determined shall conform to the requirements specified.8.2 Aproduct analysis tolerance ofTable numberA1.1 in Specification A480/A480M shall apply.The product analysis toleranceis not applicable to the carbon content for material with a specified maximum carb
42、on of .04 % or less.8.3 If the original test for product analysis fails, retests of two additional billets, lengths of flat-rolled stock, or tubes shall bemade. Both retests for the elements in question shall meet the requirements of the specification; otherwise all remaining materialA269 134in the
43、heat or lot shall be rejected or, at the option of the producer, each billet, length of flat-rolled stock, or tube may beindividually tested for acceptance. Billets, lengths of flat-rolled stock, or tubes which do not meet the requirements of thespecification shall be rejected.9. Mechanical Tests Re
44、quired9.1 Flaring Test (Seamless Tubes) One test shall be made on specimens from one end of one tube from each lot (Note 2) offinished tubes.NOTE 2The term lot applies to all tubes prior to cutting to length of the same nominal size and wall thickness which are produced from the sameheat of steel. W
45、hen final heat treatment is in a batch-type furnace, a heat-treatment lot shall include only those tubes of the same size and from the sameheat which are heat treated in the same furnace charge. When the final heat treatment is in a continuous furnace or when the heat-treated condition isobtained di
