An Overview on high manganese steel casting

摘要

Hadfield steel invented in 1882 has an enormous capacity for work-hardening upon impact and it is commonly used for railroad components such as frogs and crossings and for rock-handling equipment. It has nominal composition of iron, 1.0 to 1.4 % carbon and 10 to 14% manganese in a 1 to 10 ratio. The present paper deals with a comprehensive analysis on the overview of high manganese steel casting. The effect of chemical composition was analysed highlighting how different alloying element can affect the final mechanical properties of high manganese steel casting. Good and bad practices were reviewed, looking at how high melting temperature can course micro and macro segregation at the grain boundaries resulting in uneven wear rate and loss of strength and impact of the said steel. A Proper heat treatment cycle was discussed and typical mechanical properties and work hardening rate of the steel was also emphasised on, so as to know on which application is the steel best suited for.
