High Chromium Cast Iron: Part One :: Total Materia

As mentioned above, high chromium cast irons (HCCIs) are mainly used in mining, milling, earth-handling and manufacturing industries which require materials with exceptional wear and corrosion resistance. The exceptional wear resistance of high chromium cast irons is due to the high volume fraction of hard chromium carbides, although the toughness of the matrix also contributes to the wear resistance. The high controlled percentage of chromium

HIGH PERFORMANCE MACHINING OF HIGH CHROMIUM WEAR ...

2004). High chromium white cast irons are among the typical wear-resistant materials in which the white cast iron alloyed with 12 – 35 % chromium for achieving superior wear resistance and corrosion resistance (Pearce,1983; Tabrett,1996). The materials offer good corrosion resistance and high abrasion resistance as the result of high concentration of chromium in the matrix and the presence of eutectic

Heat Treatment of White Cast Irons Metallurgy

Because of castability and cost (much cheaper than stainless steels), high chromium (12-39% Cr) white iron castings of complex and intricate shapes are used for high temperature applications. Chromium helps to form an adherent, complex, chromium-rich oxide film which resists scaling upto 1040°C. Depending on the matrix, high chromium irons fall in three groups (carbon varies between 1-2%): 1.
