Within the text, theSI units are shown in brackets.

6、 The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard. The inch-pound units shall apply unless the “M”designation of this specification is spec

United States15.2 If a specific type of melting is required by the purchaser,it shall be as stated on the purchase order.5.3 The primary melting may incorporate separate degas-sing or refin

15、ing, 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.5.4 Steel may be cast in ingots or may be strand cast. Whensteel of different grades is sequen

16、tially 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.5.5 Tubes shall be made by a seamless process and shall becold finished.5.5.1 Seamless tubing is a tu

17、bular product 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,dimensions, and properties.5.6 The tubing shall be supplied in the cold finishedcondition followed by

18、a stress relief anneal (SRA).5.6.1 A light scale after the anneal is acceptable.5.6.2 For specification applications, the tubing may haveadditional outside surface grinding operations.6. Chemical Composition6.1 The steel shall conform to the requirements as tochemical composition prescribed in Table

19、 1.7. Heat Analysis7.1 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 obtained from one remelted ingot or theproduct of one remelted ingot of each pri

20、mary 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, the chemical composition determined from aproduct analysis made by the tubular

21、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.8. Product Analysis8.1 Except as required by 7.1, a product analysis by themanufacturer shall be required when specified on

22、the purchaseorder.8.1.1 One product analysis per heat on either billet or tubeis required.8.2 Samples for chemical analysis shall be taken in accor-dance with Practice A751. The composition thus determinedshall correspond to the requirements in the applicable sectionof Tables 1 and 2 of this specifi

23、cation and shall be reported tothe purchaser or the purchasers representative.8.3 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; otherwise all remaining

24、material in the heat or lotshall be rejected or, at the option of the producer, each billet ortube may be individually tested for acceptance. Billets or tubeswhich do not meet the requirements of the specification shallbe rejected.9. Tensile Properties9.1 The materials shall meet the mechanical prop
