Resumo

Depth of hardness of conventionally hardened forged steel work rolls can be increased through judicious selection of both alloy composition and heat treatment parameters. The use of extended austenitization and quench cycles on rolls with typical 3.25% Cr, 0.50% Mo analysis was found to produce depths of hardness similar to those created by standard heat treatment cycles applied to rolls with significantly higher alloy content. This is advantageous when the cost of raw materials and elevated processing risks for high alloy grades are taken into consideration.
