PURPOSE: To obtain the titled cast alloy with superior resistance to heat, wear and thermal shock, by restricting a composition consisting of elements such as C, Cr, Ni, Co, Ti, Al, W, Mo and Fe.
CONSTITUTION: This cast alloy with superior resistance to thermal shock, oxidation at high temp. and wear at high temp. has a composition consisting of, by weight, 0.55W1.9% C, 28W39% Cr, 25W49% Ni, 1W8% Co, 0.01W4.5% Ti, 0.01W 4.5% Al, 0.1W8% W, 0.1W9% Mo and the balance Fe with inevitable impurities. The alloy is suitable for use as the material of the guide shoe of a hot inclined rolling mill requiring said characteristics for manufacturing a seamless steel pipe. To said composition may be added 0.1W3% Si, 0.1W2% Mn, 0.005W0.2% N, 0.01W1.5% Nb or Ta, 0.001W0.2% B or Zr, etc. in a suitably combined state.
