Royal 44-30 is excellent for making repairs on all ductile and malleable irons. Royal 44-30 is also useful for the welding of other high-strength nodular and gray cast irons where maximum strength and ductility are required. The addition of manganese provides superior wetting and crack- resistant weldability on even the most difficult cast iron applications. The Royal 44-30 is also used for surfacing to improve wear resistance or for buildup. Also best for welding steel or stainless steel to cast iron.
