    Abstract: PROBLEM TO BE SOLVED: To provide an austenitic stainless steel exerting a corrosion resistance in an environment of concentrated sulfuric acid.
    SOLUTION: The austenitic stainless steel is an alloy having a composition comprising, by weight, 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, about 0.8 to about 2% copper and the balance essentially being iron and unavoidable impurities. The composition results in a low alloy content in a high-silicon austenitic stainless steel that maintains a corrosion rate that is comparable to and exceeds those of existing alloys when treating concentrated sulfuric acid. Acceptable characteristics are found when hot working is carried out in the range of about 2,100°F (1,148.9°C) to about 2,200°F (1,204.5°C). Annealing in the range of about 1,925°F (1,051.7°C) to about 2,025°F (1,107.2°C) is preferred, and rapid water quenching after annealing is also preferred.

    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 lea n 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 characteristic s were found when hot working was carried out in the range of about 2100 ~F to about 2200 ~F. Annealing in the range of about 1925 ~F to about 2025 ~F is preferred, as is rapid water quenching after annealing.
