  • Heat-resistant alloy steel for hearth metal members of steel material heating furnaces
    Patent number: 5882440
    Abstract: A heat-resistant alloy comprising, as expressed in % by weight, 0.03 to 0.1% of C, 0.2 to 0.7% of Si, 0.2 to 0.7% of Mn, 42 to 60% of Ni, 25 to 35%0 of Cr, 8 to 20% of W, over 0% to not more than 8% Mo, over 0% to not more than 5% of Co, and the balance substantially Fe. The alloy has improved resistance to compressive deformation and oxidation resistance for use in oxidizing atmospheres having a high temperature of 1250.degree. C.
