Abstract: An iron cast having iron as a major component, and including C, Si, Mn, Cr, Mo and Ni, where the cast iron provides excellent heat resistance and oxidation resistance at high temperatures. The cast iron beneficially contains between 2.5 to 3.0% of C; 2.0 to 3.0% of Si; 0.8 to 1.2% of Mn; 1.7 to 3.0% of Cr; 0.025 to 0.06% of Mg; 0.15 to 0.4% of Mo; and 17.0 to 20.0% of Ni; but less than 0.1% of P; and less than 0.02% of S. The cast iron is suitable for extremely severe conditions at high temperatures, and can be used for an exhaust manifold for engines where temperature of the manifold may reach 850° C.

Abstract: An arc chute assembly for a circuit breaker includes a plurality of U-type grids respectively including an engagement protrusion extended from each side thereof, the engagement protrusion having a key pin opening formed therethrough, a plurality of side walls respectively including a plurality of engagement slots formed therethrough, and a key pin inserted through corresponding ones of the key pin openings formed through the engagement protrusions which are inserted through the side walls and extended to an extent from an outer surface of each of the side walls. The apparatus employs the key pin for fixing the grids to the side walls, thereby facilitating assembly steps as well as decreasing an assembly time thereof.
