Answer

With respect to composition and heat treatment: Gray iron--2.5 to 4.0 wt% C and 1.0 to 3.0 wt% Si. There is no heat treatment after solidification for most gray irons.. Malleable iron--2.5 to 4.0 wt% C and less than 1.0 wt% Si. White iron is heated in a nonoxidizing atmosphere and at a temperature between 800 and 900°C for an extended period of time.
