Heat and wear resistant high alloy steel - is high nickel, chromium and cobalt contg. material together with tungsten and niobium content

摘要

A ferrous alloy of high heat and wear resistance consists of 0.3-0.5% C, 1-1.8% Si, 1-1.8% Mn, 26-30% Cr, 18-22% Ni, 0.5-6% W, 0.5-4% Nb, 18-22% Co, balance Fe. The alloy is used for rails and guides installed on the hearth of a furnace. The alloy is less susceptible to cracking and is easier to weld than UM Co-So alloy.
