Abstract: The invention relates to a duplex ferritic austenitic stainless steel having high formability utilizing the TRIP effect and high corrosion resistance with the high pitting resistance equivalent. The duplex stainless steel contains less than 0,04 weight % carbon, 0,2 - 0,8 weight % silicon, 0,3 - 2,0 weight % manganese, 4,0 - 19,0 weight % chromium, 2,0 - 5,0 weight % nickel, 4,0 - 7,0 weight % molybdenum, less than 4,5 weight % tungsten, 0,1 - 1,5 weight % copper, 0,14 - 0,23 weight % nitrogen, the rest being iron and inevitable impurities occurring in stainless steels. Further, the co-effect of the chromium, molybdenum and tungsten contents in weight % is in the range of 20

Abstract: La invención se refiere a un método para la manufactura de un acero inoxidable ferrítico-austenítico que tiene buena formabilidad y elevada elongación. El acero inoxidable es tratado con calor de manera que la microestructura del acero inoxidable contenga 45 - 75% de austenita en la condición tratada, la microestructura remanente siendo ferrita, y la temperatura Md30 medida del acero inoxidable se ajusta entre 0 y 50 °C con el fin de utilizar la plasticidad inducida por transformación (TRIP) para mejorar la formabilidad del acero inoxidable.

Abstract: The invention relates to a method for manufacturing a ferritic-austenitic stainless steel having good formability and high elongation. The stainless steel is heat treated so that the microstructure of the stainless steel contains 45 - 75 % austenite in the heat treated condition, the remaining microstructure being ferrite, and the measured M temperature of the stainless steel is adjusted between 0 and 50 °C in order to utilize the transformation induced plasticity (TRIP) for improving the formability of the stainless steel.
