Abstract
PURPOSE: To provide a martensite matrix, wear resistant cast iron having high hardness as cast, obtd. by adding a small amt. of misch metal to a Cr type wear resistant cast iron.
CONSTITUTION: The Cr type wear resistant cast iron contains C; 1.5W3.5%, Si; 0.2W1.5%, Mn; 0.2W1.5%, Cr; 5W15% and misch metal; 0.01W0.5%. Since it contains misch metal, martensite matrix is obtd. as cast even in case of sand cast small parts and die cast products which cool rapidly. Accordingly, conventional heat treatment for converting retained austenite into martensite or bainite becomes unnecessary and cast iron is obtd. having high hardeness and superior wear resistance.
