Question regarding the heat treatment of pump shafts

2016-12-13View Original

Thread Content

If the pump shaft is made of 35GrMoA or 40Gr, is it still necessary to carry out heat treatments such as quenching and tempering after it has been manufactured? I think 35GrMoA is already in a quenched and tempered state upon leaving the factory, so no further heat treatment should be required. Am I correct?

My main question is whether heat treatment is still necessary after turning the bar material. Or should the rod be heat-treated before turning?
