White Cast Irons with High Abrasion Resistance and Hardness

White Iron is unalloyed cast iron with low carbon and silicon content such that the structure is hard brittle iron carbide with no free graphite.These irons are limited in application because of the lack of impact resistance and the difficulty in maintaining the structure in thicker sections.Wear Properties of Austempered Ductile Ironsdevelop product to take advantage of the performance characteristics of ADI.Wheelebrator Inc.[9] found in a study that ADI is adequate in chain conveyors but the material is outperformed by manganese steel in blast cabinet housings and white iron in vanes and liners.A comparative test performed by the authors betweenUS4576875A - Weldable wear part with high wearA wear part with high wear and abrasion resistance combined with unlimited weldability and good mechanical strength or toughness,comprising a composite part of hard metal portion,a cast metal alloy body portion and attached thereto to joining portion,characterized in that the joining portion consists essentially of a weldable steel which by casting is bonded to the cast metal alloy body
