Abstract

La invención se refiere a un acero inoxidable dúplex, ferrítico austenítico que tiene alta formabilidad y que utiliza el efecto TRIP y una alta resistencia a la corrosión con elevado equivalente de resistencia a corrosión por picaduras. El acero inoxidable dúplex contiene menos de 0.04% en peso de carbono, 0.2 - 0.8 % en peso de silicio, 0.3 - 2.0 % en peso de manganeso, 4.0-19.0 % en peso de cromo, 2.0-5.0 % en peso de níquel, 4.0-7.0 % en peso de molibdeno, menos de 4.5 % en peso de tungsteno, 0.1-1.5 % en peso de cobre, 0.14-0.23 % en peso de nitrógeno, el resto siendo fierro e impurezas inevitables que ocurren en los aceros inoxidables. Además, el co-efecto de los contenidos de cromo, molibdeno y tungsteno en % peso está en el rango de 20<(Cr+Mo+0.5W)<23.5, en donde la proporción Cr/(Mo+0.5W) está en el intervalo de 2.0-4.75.
