THERMAL RESISTANT STEEL ALLOY FOR GRATE BAR OF SINTERING MACHINE

摘要

PURPOSE: Provided is a steel alloy for grate bar of sintering machine, which has improved mechanical property by adding Ni, Mo or W in conventional Cr-based heat resistant alloy containing 26-28wt.% of Cr. CONSTITUTION: The heat resistant steel alloy comprises 26-28wt.% of Cr, 1.0-15wt.% of C, 1.7-2.0wt.% of Si, 0.8-1.2wt.% of Mn, 0.04wt.% or less of P, 0.03wt.% or less of S, 0.5-5wt.% of one or more elements selected from Ni, W, Mo, a balance of Fe and other unavoidable impurities.
