Abstract:  
The present invention broadly relates to the art of metal treatment. The invention particularly relates to a method of producing ferrous castings and the casting so produced. This application is a continuation in part of my applications Serial No. 23,858, filed April 28, 1948, now abandoned, entitled Manufacture of Malleableized Iron Castings Particularly Wearing Parts of Agricultural Implements, and Serial No. 384,313, filed October 5, 1953, and entitled, Heat Treated Malleable Cast Iron and Methods of Producing the Same. More particularly the invention relates to the producing of ferrous castings having markedly increased physical properties as compared with known castings, with particular reference to cast parts that are subjected to wear under various abrasive conditions.
