An H-type base alloy or a high silicon base alloy contains additions of about 0.6% to 2.5% copper and 0.55% to 2.65% microalloying amounts of the group 0.2% to 0.85% tungsten, 0.2% to 0.85% molybdenum, 0.1% to 0.5% columbium and 0.05% to 0.45% titanium.

Abstract: Air-meltable, castable, machinable, hardenable alloys that are resistant to highly corrosive and abrasive slurries, especially those employed in the handling of wet-process phosphoric acid reactor fluids or hot concentrated sulfuric acid. The alloys consist of, by weight, about 11% to about 40% nickel (plus cobalt), about 27% to about 42% chromium, about 1% to about 4% copper, about 3% to about 4.5% silicon, about 0.7% to about 2% carbon, about 0.3% to about 3% manganese, up to about 4.5% molybdenum, and the balance essentially iron plus the usual minor impurities.
