4. Materials and Manufacture
4.I The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth electric-furnace, or basic-oxygen,
4.2 If steels of different grades are sequentially strand cast dentification of the resultant transition material is required The steel producer shall remove the transition material by any established procedure that positively separates the grades.
4.3 The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding to a minimum of 1000F (540C] so that no untempered martensite remains, or otherwise processed in such a manner that no untempered martensite remains,
4. 4 When pipe is cold expanded, the amount of expansion shall not exceed 12 %o of the specified outside diameter of the pipe.
