Abstract: The invention relates to a stainless steel exhibiting transformation-induced plasticity (TRIP) effect resistant to delayed cracking and to the method for producing the stainless steel. The resistance to delayed cracking in the stainless steel is achieved limiting the total hydrogen content of the stainless steel measured by inert gas fusion method below 4 weight ppm, preferably below 3 weight ppm by a heat treatment performed at the temperature range between 100° C and 700° C for 0.1 - 300 hours, preferably at 200 - 600° C for 1-100 hours, and more preferably at 250-500°C for 1-100 hours.

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.
