This paper focuses on the duplex stainless steel processability and
presents many practical technological approaches which are applied in many steel
companies on how to improve the processability. First, take into consideration an
appropriate hot working temperature; second, make sure cooling rate higher than
15℃/s; and third, conduct annealing treatment before delivery.
