 Quality at heat treatment
It has a great importance to control the tool steel after heat treatment if these steels have gained the desired mechanical properties for service conditions.
The microstructural changes that occured during the heat treatment process and its effect to mechanical properties shouldn’t be controlled only hardness measurement for today’s high performance tools and dies.
It is possible to get the same hardness value with different kind of microstructures but grain size, carbide precipitation during quenching has a great role on the toughness and high temperature strenght of the hot work tool steels which are going to be used in high pressure die casting , forging or extrusion applications. Because of that reason it is really necessary to control grain size , banding, microsegregation and carbide distribution just before and after the heat treatment process by using the necessary references charts.
In TAMÇELİK micro and macro controls applied by well trained staff refering to the international standarts. The controls hold with fully renewed laboratory equipments and could be record on computer and microstructure report of the tools can be prepared for the customer demands. |
