This specification covers seamless stainless steel tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed. The steel may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The tubes shall be made by a seamless process and by either cold working or hot working as specified. Seamless stainless steel tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel and then cold finishing the hot-worked tubing to produce the desired shape, dimensions and properties All austenitic tubes shall be furnished in the annealed condition. An analysis of each heat of steel shall be made to determine the percentages of the elements specified. If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt.
