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 purc
27、hase order.4.3 The primary melting may incorporate separate degassing or refining, and may be followed by secondary melting, such aselectroslag or vacuum-arc remelting. If secondary melting is employed, the heat shall be defined as all of the ingots remelted froma single primary heat.4.4 Steel may b
28、e cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identificationof the resultant transition material is required. The producer shall remove the transition material by an established procedure thatpositively separates the grades.4.5 Tubes shall be mad

Chemical Composition5.1 The steel shall conform to the requirements as to chemical composition prescribed in Table 1 or Table 2 (See SpecificationA1040). If no grade is specified, Grades MT 1
30、010 to MT 1020 may be furnished. Analyses of steels other than those listed areavailable. To determine their availability, the purchaser should contact the producer.5.2 When a carbon steel grade is ordered under this specification, supplying an alloy grade that specifically requires the additionof a
31、ny element other than those listed for the ordered grade in Tables 1 and 2 is not permitted.5.3 Mechanical tubing with improved ductility may be produced from Drawing Steel (Types A and B), Deep Drawing Steel,or Extra Deep Drawing Steels identified in Specifications A1008/A1008M, A1011/A1011M, or A1

Heat Analysis6.1 An analysis of each heat of steel shall be made by the steel manufacturer to determine the percentages of the elementsspecified; if secondary melting processes are e
33、mployed, the heat analysis shall be obtained from one remelted ingot or the productof one remelted ingot of each primary melt. The heat analysis shall conform to the requirements specified, except that where theheat identity has not been maintained or where the analysis is not sufficiently complete
