    Abstract: Una composición de acero inoxidable austenítico que incluye niveles relativamente bajos de níquel y molibdeno, y que presenta resistencia a la corrosión, resistencia a la deformación a temperaturas elevadas y propiedades de formabilidad comparables a ciertas aleaciones que incluyen niveles elevados de níquel y molibdeno. Modalidades del acero inoxidable austenítico incluyen, en porcentaje en peso, hasta 0.20% de C, 2.0-9.0% de Mn, hasta 2.0% de Si, 16.0-23.0% de Cr, 1.0-7.0% de Ni, hasta 3.0% de Mo, hasta 3.0% de Cu, 0.05- 0.35% de N, hasta 4.0% de W, (75(%C)) = (Nb+Ti+V+Ta+Zr) = 1.5, hasta 0.01% de B, hasta 1.0% de Co, hierro e impurezas. Además, modalidades del acero pueden incluir 0.5 = (Mo+W/2) 5.0 y/o 1.0 = (Ni+Co) s 8.0.

    Abstract: An alloy having a composition, by weight, of about 0.025 % or less carbon, about 0.5 to about 4.1 % manganese, about 5.5 to about 6.2 % silicon, about 11 to about 15 % chromium, about 9.0 to about 15.5 % nickel, about 0.8 to about 1.2 % molybdenum and about 0.8 to about 2 % copper and the remainder being essentially iron with incidental impurities. This composition results in lean alloy content in a high silicon austenitic stainless steel for concentrated sulfuric acid service while maintaining a corrosion rate similar to and competitive with existing alloys for such service. Acceptable characteristics were found when hot working was carried out in the range of about 2100 .degree.F to about 2200 .degree.F. Annealing in the range of about 1925 .degree.F to about 2025 .degree.F is preferred, as is rapid water quenching after annealing.
