What are the consequences of direct quenching and tempering of castings?
The foundry should deliver the goods in an annealed state, so there is no problem with your process. If there is no annealing, but the shape of the workpiece is simple and the technical requirements are not high, your process will be fine. On the contrary, it is recommended that you anneal or normalize. Direct conditioning+surface treatment may be easy to deform or crack. []
