Abstract

PURPOSE: To enhance the heat resistance and mechanical strength of a grate material by adding specified amounts of C, Si, Mn, P, S and Mg to the material, adjusting the amount of carbide to a specified amount or less, and providing a ferrite matrix as cast.
CONSTITUTION: To steel for a grate material are added, by wt., 2.7W4.7% C, 3.5W4.5% Si, 0.2W0.7% Mn, <0.2% P, <0.04% S and 0.03W0.08% Mg, the amount of carbide after casting is adjusted to ≤10wt%, and a ferrite matrix is provided as cast. The resulting nodular graphite cast iron has superior heat resistance and mechanical properties, and it is inexpensive.
