The hardness and retained austenite in the matrix of the cast iron could be widely controlled, and it was found that the remarkable secondary hardening due to precipitation of special carbides made the matrix hard and strong enough to the practical applications.
The excellent performance of hot work roll made of the multi-alloyed white cast iron was proved by the field test.
This type of cast iron is gradually being applied to the pulverizing mill rolls and that a good performance has been reported in the cement industry.
It is convinced that the multi-alloyed white cast iron will also find wider applications as abrasion wear resistant materials.
