Stress Relieving Furnace

Stress Relieving Furnace

Components such as welded structures, cold drawn or formed items require stress relieving as stresses are induced in these processes which will deform the components after they are put in use. Our bogie hearth furnaces for stress relieving or stress relief annealing are available with standard configuration as well as configurations custom for the user’s job profile and volume.

For lower stress relieving temperatures, 750°C and below a centrifugal fan-based circulation system with stainless steel louvers is implemented to assure adequate convective heat transfer. For higher temperatures, the design is based on radiation heat transfer without air circulation.
