15、d States14. 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 may incorporate separate degas-sing or refining, and may be followed by secondary melting,s
16、uch 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 cast. Whensteel of different grades is sequentially strand cast, identifica-tion of the resu
17、ltant 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 a seamless process and shall beeither hot finished or cold finished, as specified.4.6 Seamless tubing is a tubular produc
18、t made without awelded seam. It is manufactured usually by hot working steeland, if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimen-sions and properties.5. Chemical Composition5.1 The steel shall conform to the requirements as tochemical c
19、omposition prescribed in Table 1 (Low Carbon MTGrades), Table 2 (Higher Carbon Steels), Table 3 (AlloyStandard Steels (see Guide A1040) and Table 4 (Resulfurizedor Rephosphorized, or Both, Carbon Steels (see GuideA1040).5.2 Grade MT1015 or MTX1020 will be supplied at theproducers option, when no gra
20、de is specified.5.3 When a carbon steel grade is ordered under thisspecification, supplying an alloy grade that specifically re-quires the addition of any element other than those listed forthe ordered grade in Table 1 and Table 2 is not permitted.5.4 Analyses of steels other than those listed are a
21、vailable.To determine their availability, the purchaser should contact theproducer.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 used, theheat analysis shall be
22、obtained from one remelted ingot or theproduct of one remelted ingot of each primary melt. The heatanalysis shall conform to the requirements specified, exceptthat where the heat identity has not been maintained or wherethe analysis is not sufficiently complete to permit conformanceto be determined,
23、 the chemical composition determined from aproduct analysis made by the tubular manufacturer shallconform to the requirements specified for heat analysis. Whenrequested in the order or contract, a report of such analysesshall be furnished to the purchaser.7. Product Analysis7.1 Except as required by
24、 6.1, a product analysis by themanufacturer shall be required only when requested in theorder.7.1.1 Heat Identity MaintainedOne product analysis perheat on either billet or tube.7.1.2 Heat Identity Not MaintainedA product analysisfrom one tube per 2000 ft (610 m) or less for sizes over 3 in.(76.2 mm
25、), and one tube per 5000 ft (1520 m) or less for sizes3 in. (76.2 mm) and under.7.2 Samples for chemical analysis, except for spectrochemi-cal analysis, shall be taken in accordance with Practice E59.The composition thus determined shall correspond to therequirements in the applicable section or Tab
26、les 1-5 of thisspecification and shall be reported to the purchaser or thepurchasers representative.7.3 If the original test for check analysis fails, retests of twoadditional billets or tubes shall be made. Both retests for theelements in question shall meet the requirements of thespecification; ot
