Stress Relief Annealing

Stress relief annealing removes residual stresses induced by welding, machining, or cold working without significantly changing mechanical properties.

The metal is heated to a lower temperature (450–650°C) and slowly cooled.

Furnace Types Used:

  • Electric furnace
  • Gas-fired furnace
  • Batch furnace

Applications:
Welded structures, machine beds, pressure vessels
