<p>The present invention relates to white iron alloys having a ferritic matrix and a dispersed phase and which exhibit enhanced combined corrosion and abrasion resistance in hot slurries, such as those formed in the production of raw phosphoric acid, and containing from between about 0.75% to 1.5% carbon, between about 2.0% to 2.5% manganese, between about 2.0 to 3.0% molybdenum, between about 1.0% to 2.0% copper, up to about 0.85% silicon, between about 0.5% to 1.0% tungsten, between about 24 to 30% chromium, the balance being iron along with normal residual elements, the alloys being castable and age-hardenable.</p> |
