摘要：

Cold drawn ERW pipes sometimes show the difficulty in formability during cold working, expanding, and swaging because of the difference in recrystallization behaviors between the welded zone and base metal in cold drawing. In this report, recrystallization behavior was on the results, a uniform recrystallized microstructure is established by post heat treatment of the welded zone or control of the chemical composition and rolling conditions in manufacturing of hot-rolled coils. Cold drawn ERW pipes with superior formability ar thus produced.
