Balls casting simulation and practice for Hadfield Stell
The balls casting is done in 12 sand moulds fon balls, with central feeding and outlet gating for each set of 6 balls. For the simulation in which the casting system is symmetrical, like in our case, in order to reduce the simulation time, the software allows simulating only a quarter of the casting mould, according to Fig.2.

Characteristics of Hadfield steel: composition, application
Heat treatment of Hadfield steel directlydepends on the carbon content of the alloy. The higher the carbon level, the higher the temperature should be. For example, if in the alloy it is at the level of 1%, then the temperature should be not lower than 900 degrees. If carbon is 1.5%, then processing is possible at 1000 degrees.
