When steel of different grades are sequentially strand cast, identificationof the resultant transition material is

42、required. The producer shall remove the transition material by an established procedure thatpositively separates the grades.6. Materials and Manufacture6.1 The tubes shall be made from flat-rolled steel by an automatic welding process without the addition of filler metal.7. Condition7.1 The tubes sh

43、all be furnished in any of the following conditions as specified:7.1.1 As welded,7.1.2 Welded and annealed,7.1.3 Cold reduced,7.1.4 Cold reduced and annealed.7.2 The inside diameter bead shall be furnished in any of the following conditions as specified:7.2.1 Bead not removed,7.2.2 Bead controlled t

44、o 0.005 in. (0.13 mm) or 15 % of the specified wall thickness, whichever is greater, and7.2.3 Bead removed.7.3 Square and rectangular welded stainless tubing is supplied as cold worked unless otherwise specified.8. Heat Analysis8.1 An analysis of each heat of steel shall be made by the steel manufac

45、turer to determine the percentages of the elementsspecified. If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot or the productof one remelted ingot of each primary melt. The chemical composition thus determined, or that determined from a product

46、analysismade by the tubular product manufacturer, shall conform to requirements specified. When requested in the order or contract, areport of this analysis shall be furnished to the purchaser. (See Test Methods, Practices, and Terminology A751.)9. Permissible Variations in DimensionsRound Tubing9.1

47、 For all conditions except tubing with bead removed, Table 2 shall apply.9.2 For tubing with bead removed, Table 3 shall apply.9.3 LengthsTubing is normally furnished in mill lengths 5 ft (1.5 m) and over. Definite cut lengths are furnished whenspecified, to the length tolerances shown in Table 4. F

48、or tubing ordered in multiple lengths, it is common practice to allow a definiteamount over for each multiple for the purchasers cutting operation. Thus cutting allowance should be specified in the purchaseorder.A554 155TABLE 2 Diameter, Wall,A and Ovality Tolerances (All Conditions Except Tubing wi
