Duplex stainless steels are made from the 1960s and stainless steels are the most recent family. These twin classes are called because of the two phases of their mineral structure, the austenitic (face-centered cube knitting) and the ferrite (physical cube knitting) in almost equal proportion. They use their good mechanical properties such as actors (that are the State) and / or their best corrosion resistant symptoms (specifically emphasize the corrosion material). Grade 1.4462 Grade was initially developed. They offer high corrosion resistance, but the processing is very difficult. Wrong processing is advised to deal with poor performance and respectable customers, suppliers / processors. The latest type of high dual steel ER Double Dip at 1.4658 stainless steel grade (designated HDSS). "Modern, double stainless steels, chromium (CR), molybdenum / tungsten (m / m) nitrogen (N) and nickel (n) improve., New, mixed double stainless steels combine to increase unpleasant levels Resistance to the risk of creating a random intermediate phase .
