For high durability and performance of tools needed to work part of them had the suitable hardness and wear resistance. This is possible through the creation of a core of fine-grained martensitic structure, which is achieved by pre-forging and isothermal annealing before machining and after machining — quenching and tempering. For these thermal processes are ….  Read More
