Abstract
PURPOSE:To make the impact value of the title ductile iron higher than that of the conventional alloy tool steel by adding Mo, V, W, etc., separately or compositely to the base alloy component of the ductile iron, and then austempering the iron under specified conditions. CONSTITUTION:The base alloy component contains, by weight, 3.0-4.0% C, 2.0-3.5% Si, 0.1-0.9% Mn, <=2.0% Cu, and <=2.0% Ni. One or more kinds among 0.2-2.0% Mo, 0.2-2.0% Cr, 0.2-2.0% V, and 0.2-2.0% W are further added to the ductile iron of the above-mentioned composition, and the balance consists of Fe and trace impurities. The iron is kept at 820-950 deg.C for 0.5-5hr, then immediately quenched to 220-400 deg.C, kept at that temp. for >=0.5hr, and austempered. The ductile iron has high wear resistance, and can be used for the punching die, etc., for cold pressing and various sliding parts.
