High-chromium white iron is an erosion resistant ferrous alloy widely used in manufacturing, it has for long been applied to components in mining and minerals industry due to its excellent abrasion resistance, imparted by the hard alloy eutectic carbides present in the microstructure.
High Chrome White Iron (ASTM A532) High chrome white iron is composed of Carbides and Martensite (among the hardest phase of iron alloys). This combination makes chrome white iron exceptionally wear-resistant and strong, but gives it virtually no toughness.
Wear and Abrasion Resistant Cast Irons (White Irons) Click here for the Metallurgy of Cast Iron. White cast irons are widely used in abrasive wear applications involved in the crushing, grinding, milling and handling of abrasive materials such as minerals and ores, both dry and as slurries.
High-chromium white iron alloys allow massive castings (for example, a 10-tonne impeller) to be sand cast, as the chromium reduces cooling rate required to produce carbides through the greater thicknesses of material.
