<p>A high-Ni, high-Cr, iron alloy having excellent heat resistance, wear resistance, and thermal shock resistance, which can be used as an alloy for guide shoe of inclined hot-rolling mill for manufacturing seamless steel pipes and as an alloy for padding. It comprises 0.55 to 1.9 % C, 28 to 39 % Cr, 25 to 49 % Ni, 0.01 to 4.5 % Ti, 0.01 to 4.5 % Al, 0.1 to 8 % W, 0.1 to 9 % Mo, and the balance substantially consisting of iron. If necessary, it can contain 0.1 to 3 % Si, 0.1 to 2 % Mn, 1 to 8 % Co, 0.005 to 0.2 % N, 0.01 to 1.5 % Nb or Ta, 0.001 to 0.2 % B or Zr (all % by weight).</p> |
