Ladle-treated high manganese steel reinforced by Cr7C3 phase

This research programme was designed to study the effect of chromium addition on the characteristic properties of Hadfield steel that has been produced by using the ladle treatment process. Chromium-containing ladle-treated Hadfield steel and chromium-free ladle-treated Hadfield steel have been produced, comparing with the Hadfield steel that has been produced by the conventional process. It has been found that chromium addition has a significant effect on the characteristic properties of the ladle-treated Hadfield steel. For instance, wear abrasion resistance was enhanced approximately five times much higher than conventional Hadfield steel. Moreover, an industrial trial indicates that chromium-containing ladle-treated Hadfield steel has significant benefits from the perspective of performance, and production cost as well.
