Low hydrogen annealing

Low hydrogen annealing is a heat treatment in metallurgy for the reduction or elimination of hydrogen in a material to prevent hydrogen embrittlement.

Process description

The material is kept in a hydrogen annealing oven over several hours at temperatures between 200 °C and 300 °C. The enclosed hydrogen atoms, known for hydrogen embrittlement[1] are removed by effusion. The method is predominantly used immediately after welding, coating process or galvanizing of the parts.
