Materials and Manufacture6.1 The steel may be made by any process.6.2 If a specific type of melting is requir

40、ed by the purchaser, it shall be as stated on the purchase order.6.3 The primary melting may incorporate separate degassing or refining and may be followed by secondary melting, such aselectroslag remelting or vacuum-arc remelting. If secondary melting is employed, the heat shall be defined as all o

41、f the ingotsremelted from a single primary heat.6.4 Steel may be 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 proce

42、dure thatpositively separates the grades.6.5 The tubes shall be made by a seamless process and by either cold working or hot working as specified. Seamless steel tubingis a tubular product made without a welded seam. It is usually manufactured by hot working steel and then cold finishing thehot-work

43、ed tubing to produce the desired shape, dimensions, and properties.7. Condition7.1 Round seamless stainless mechanical tubing is generally supplied in the cold-worked and annealed condition (see 5.27.2through 5.57.5). Square, rectangular, or other shapes of tubing are generally supplied annealed pri

44、or to final cold shaping. If someother condition is desired, details shall be included in the order. Round seamless hollow bar is generally applied in the hot-workedand annealed condition.7.2 The thermal treatment for ferritic and martensitic steels shall be performed by a method and at a temperatur

45、e selected bythe manufacturer unless otherwise specified by the purchaser.7.3 Unless otherwise specified, all austenitic tubes mechanical tubing and hollow bar, except for UNS N08020 shall befurnished in the solution annealed condition. Unless otherwise specified in Table 4, the solution anneal shal

46、l consist of heating thematerial to a minimum temperature of 1900 F 1040 C and quenching in water or rapidly cooling by other means.Alternatively,immediately following hot forming while the temperature of the tubes mechanical tubing or hollow bar is not less than the specifiedminimum solution treatm

47、ent temperature, tubes may be individually quenched in water or rapidly cooled by other means. Thissolution anneal shall precede final cold work, when cold-worked tempers are required.
