Definitions

  • Such alloys are particularly desirable instead of ceramic refractories and the like in rollertype furnaces and slab heaters as well as in radiant heat tubes and the like which are openated in the temperature range of 2400 F.
  • Conventional alloys used for applications in this temperature range have not been satisfactory for most uses because of the high rate of creep, corrosion and lack of strength at temperatures at or about 2200 F. to 2500 F.
  • Example I A group of alloys were melted to evaluate the effectiveness of various combinations within the broad range of the invention in creep control at 2400 F. The alloys were formed and tested at 2400 F. in a standard cantilever creep test using 250 lb./in. loading with the following results:
  • Example II A series of alloys were melted at the 14% tungsten level with various carbon contents to determine the effect of carbon. The results are plotted in FIGURE 2.
  • Example III A series of alloys at 0.6% carbon and at 0.4% carbon with varying tungsten were made. The chromium content was 30% and the nickel varied with tungsten to produce a nickel and tungsten content of in FIGURE 3. In
  • FIGURE'4 the nickel content was maintained at 48% and the chromium varied with tungsten to produce a chrmium and tungsten content of 50%.
  • the stress rupture data are set out in the following table:
  • a low creep, high strength alloy resistant to corrosion and thermal shock at temperatures up to 2500 F. consisting essentially of an etfective amount upto about 1.0% carbon to provide high strength, corrosion resistance and low creep at elevated temperatures, about 26% to 38% chromium, up to about 0.2% manganese, up to about 0.2% silicon, about 10% to 25% tungsten and the balance nickel with residual impurities in ordinary amounts.
  • a low creep, high strength alloy resistant to corrosion and thermal shock at temperatures up to 2500 F. consisting essentially of about 0.20% to 0.75% carbon, about 28% to 35% chormium, up to about 0.2% manganese, up to about 0.2% silicon, about 13% to 19% tungsten and the balance nickel with residual impurities in ordinary amounts.
  • a low creep, high strength alloy resistant to corrosion and thermal shock at temperatures up to 2500 F. consisting essentially of about 0.5% carbon, about 31% chromium, about 17% tungsten and the balance nickel with residual impurities in ordinary amounts.
