Definitions

  • Alloy C Mn Si Ni Cr W S Bal Alloy 1 Fe usual impurities Alloy 11 Fe usual impurities Alloy l is a recognized high temperature alloy having extraordinary stress rupture characteristics as compared with most alloys. It is sold by Blaw-Knox Company under the trade mark Mo Re No. 1 for high temperature and high stress application.
  • Alloy 11 is a composition according to the present invention.
  • test piece formed from Alloy No. 1 developed hours of life.
  • test piece formed from Alloy No. 2 developed 883 hours of life, or almost 9 times the life of the best alloy heretofore available for high temperature high stress applications. This is a very surprising result.
  • a low creep, high strength alloy resistant to corro sion and thermal shock at elevated temperatures and having unusual stress rupture characteristics at elevated temperatures consisting essentially of about 0.3% to 0.9% carbon, about 20% to 30% chromium, about to 35% nickel, about 0.8% to 4% manganese, about 0.9% to 3.5% silicon, about 0.3% to 5% tungsten, about 0.030% to about 0.15% sulfur and the balance iron with residual impurities in ordinary amounts.
  • a low creep, high strength alloy resistant to corrosion and thermal shock at elevated temperatures having unusual stress rupture characteristics at elevated temperatures consisting essentially of about 0.35% to 0.75% carbon, about 20% to 30% chromium, about 30% to 35% nickel, about 1.2% "to 2.4% manganese, about 1.2% to 2.5% silicon, about 1.75%% to 5% tungsten, about 0.035% to 0.10% sulfur and the balance iron with residual impurities in ordinary amounts.
