发明名称 Annealing and pickling method of duplex stainless steel and duplex stainless steel manufactured using the same
摘要 PURPOSE: An annealing and pickling method for duplex stainless steel and duplex stainless steel manufactured by the same are provided to reduce pickling failures by employing a mechanical surface grinding method. CONSTITUTION: An annealing and pickling method for duplex stainless steel(10a) includes annealing and pickling processes(30). Grinding(31a-31c) is implemented one or more times between the annealing and pickling processes or in the pickling process by using heavy or abrasive brushes(33a,33b,33c) at an 1000-1300 RPM range.
