The as-cast structure of HG785D steel plate is usually composed of austenite, carbide and pearlite, and sometimes contains a small amount of phosphorus eutectic. When the amount of carbide is large, it often appears in a network on the grain boundary. Therefore, the high-manganese steel in the as-cast structure is very brittle and cannot be used, and it requires a solution treatment. The commonly used heat treatment method is solid solution treatment, that is, steel is heated to 1050 ~ 1100 ° C, and the as-cast microstructure is eliminated by heat preservation to obtain a single-phase austenite structure, and then water quenched to maintain this structure to normal temperature.
