HEAT TREATMENT

The heat treatment of cast steel is a process step for setting the manufacturing and usage properties. The material and wall thickness of the casting are of decisive importance for determining the process parameters, such as heating and cooling rates, temperature and holding times.

The heat treatment is carried out according to the physical requirements of the materials
the corresponding spectrum. This includes i.a. quenching and tempering, stress relief annealing,
Solution annealing through to diffusion annealing: with furnace temperatures of up to 1,250 degrees.

Heat treatment is understood to mean processes for treating materials by thermal, chemical-thermal or mechanical-thermal effects, with the aim of achieving optimized properties for a specific purpose.

In heat treatment, a fundamental distinction is made between processes that bring about a radical structural transformation and processes that only cause a transformation on the surface of a workpiece. The former processes include, for example, annealing and hardening; H. the thermal processes. The second-mentioned processes belong to the diffusion and coating processes or to the thermochemical processes.
