摘要
PROBLEM TO BE SOLVED: To improve the carburizing resistance and metal dusting resistance of a tubing, such as a reheater tube for a direct reduction iron making furnace and a cracking tube for ethylene production.;SOLUTION: The alloy has a composition consisting of, by weight, 0.05-0.6% C, ≤2.5% Si, 1.5-6% Mn, 23-46% Cr, 23-50% Ni, at least one kind selected from the group consisting of ≤6% W, ≤2% Nb and ≤2% Mo, and the balance essentially Fe. If necessary, 0.005-0.25% Ce, 0.01-0.5% Al, 0.01-0.4% Ti and 0.01-0.3% Zr can be incorporated.;COPYRIGHT: (C)2001,JPO
