Mechanical casting parts how to improve the toughness of the steel? Water toughening treatment can improve some organization in order to improve the toughness of austenitic steel, the mechanical casting steel heated to high temperatures to dissolve excess phase, then water-cooled heat treatment process. Mechanical steel water toughening treatment for an actual solid solution treatment, commonly used in high manganese steel casting, due to high as-cast organization for austenitic manganese steel, carbide and a small amount of pearlite phase transformation products. Precipitate along austenite grain boundary carbides decrease the toughness of the steel, to eliminate carbides, heat the steel to austenitic area temperature, and heat preservation for a period of time, the carbide in the as-cast organization basically solid solution in the austenite, and then to quenching in water, resulting in a single austenitic organization, it can improve the toughness of the steel.
