Materials and Manufacture4.1 The steel may be made by any process.4.2 If a specific type of melting is required by the purchaser,it shall be as stated on the purchase order.4.3 The primary melting
17、may incorporate separate degas-sing or refining, and may be followed by secondary melting,such as electroslag or vacuum-arc remelting. If secondarymelting is employed, the heat shall be defined as all of theingots remelted from a single primary heat.4.4 Steel may be cast in ingots or may be strand c
18、ast. Whensteel of different grades is sequentially strand cast, identifica-tion of the resultant transition material is required. Theproducer shall remove the transition material by an establishedprocedure that positively separates the grades.4.5 Tubes shall be made by the electric-resistance-welded
19、process and shall be made from hot- or cold-rolled steel asspecified.5. Chemical Composition5.1 The steel shall conform to the requirements as tochemical composition prescribed in Table 1 or Table 2 (SeeSpecification A 1040). If no grade is specified, Grades MT1010 to MT 1020 may be furnished. Analy
20、ses of steels otherthan those listed are available. To determine their availability,the purchaser should contact the producer.5.2 When a carbon steel grade is ordered under this speci-fication, supplying an alloy grade that specifically requires theaddition of any element other than those listed for
21、 the orderedgrade in Tables 1 and 2 is not permitted.6. Heat Analysis6.1 An analysis of each heat of steel shall be made by thesteel manufacturer to determine the percentages of the ele-ments specified; if secondary melting processes are employed,the heat analysis shall be obtained from one remelted
22、 ingot orthe product of one remelted ingot of each primary melt. Theheat analysis shall conform to the requirements specified,except that where the heat identity has not been maintained orwhere the analysis is not sufficiently complete to permitconformance to be determined, the chemical compositiond
23、etermined from a product analysis made by the tubularmanufacturer shall conform to the requirements specified forheat analysis. When requested in the order or contract, a reportof such analysis shall be furnished to the purchaser.7. Product Analysis7.1 When requested on the purchase order, a product
24、 analy-sis shall be made by the supplier. The number and source ofsamples for such product analysis shall be based on theindividual heat or lot identity of one of the following forms ofmaterial:7.1.1 Heat Identity MaintainedOne product analysis perheat shall be made on either the flat-rolled stock o
25、r tube.7.1.2 Heat Identity Not MaintainedA product from onetube per 2000 ft (610 m) or less for sizes over 3 in. (76.2 mm),and one tube per 5000 ft (150 m) or less for sizes 3 in. andunder.7.2 Samples for product analysis except for spectrochemicalanalysis shall be taken in accordance with Practice
26、E 1806. Thecomposition thus determined shall correspond to the require-ments of Tables 1-3.7.3 If the original test for product analysis fails, retests oftwo additional lengths of flat-rolled stock or tubes shall bemade. Both retests for the elements in question shall meet therequirements of the spe
27、cification; otherwise, all remainingmaterial in the heat or lot shall be rejected or, at the option ofthe producer, each length of flat-rolled stock or tube may beindividually tested for acceptance. Lengths of flat-rolled stockor tubes which do not meet the requirements of the specifica-tion shall b

Permissible Variations in Dimensions for RoundTubing8.1 Diameter and Wall Thickness (Hot-Rolled Steel)Variations from specified outside diameter for “as-welded” and“as-welded and annealed” tubing made from hot-rolled steelshall not exceed the amounts prescribed in Table 4. Permissiblev

Permissible variations in wall thickness for tubing thathas been sink-drawn for closer tolerances on outside diametersare 610 % of the nominal wall or 60.010 in. (0.25 mm),
