Heat resisting tests of aluminized cast iron, in the air, coal gas, and coal gas with 10% by volume H2S, were carrid out at 800°C, 900°C and 1000°C, respectively. The results were as follows:
Aluminized cast iron has generally better heat resistance than non-aluminized cast iron. It has poorer resistance in coal gas than in the air, the poorest being in the coal gas with H2S gas.
