Abstract

An iron is melted, and then treated with alloys to obtain a compsn. by wt. of 0.2% P, and 0.1-3% Cr, Ni, Cu and/or Mo, all these % being w.r.t. the % Fe. Next, 0.02-0.5% Ti, Zr, Hf, V, Nb, Ta and/or W are added w.r.t. the total wt. of the melt, followed by an inoculant. The inoculant pref. converts 5-50% of the carbonitride forming elements present to nitrides, esp. by using max. 0.1 wt.% inoculant w.r.t. the % Fe. The castings are pref. used for parts subjected to high temp., or thermal shock, esp. in IC engine exhaust systems. Used for exhaust pipe elbows which still possess adequate strength after more than 100,000 km when used on an IC engine in a motor car.
