            Technical requirements for duplex stainless steel
            Time:2011-6-3
                4, duplex stainless steel smelting process:
            1) The medium frequency electric furnace, strict control of steel temperature.
            2) The ratio of strictly material, the chemical composition of duplex stainless steel strict control, especially nitrogen directly determines the content of the performance of dual phase steel, the company uses a unique technology, strict to ensure that the content of nitrogen.
            3) According to the characteristics of duplex stainless steel components, the strict implementation of heat treatment.
                5, duplex stainless steel heat treatment requirements:
            Duplex Stainless Steel Heat Treatment: The solution treatment.
                6, duplex stainless steel machining process:
            According to different requirements of the part, I have developed for each part of the strict process to ensure that the processing of qualified parts.
                 7, the duplex stainless steel of the test:
            1) The chemical composition test.
            2) The microstructure examination.
            3) mechanical properties.
