Industrial batch ovens deliver hydrogen embrittlement relief of aerospace parts

Wisconsin Oven Corp. has shipped three gas-fired batch ovens to an aerospace parts manufacturer for hydrogen embrittlement relief of chrome-plated landing gear.

During the hydrogen embrittlement relief process, various parts are placed on a pallet in the heat-treating oven for periods up to 24 hours. The heating allows the hydrogen trapped in the chrome plating to be released.

The ovens have a maximum temperature rating of 500 degrees F and work chambers of 7 ft. by 13 ft. by 2 ft. 6 in. They are designed with horizontal airflow, which is suitable for products arranged on multiple tiers when heated airflow cannot be directed vertically through the product. The adjustable ductwork can be set for optimum airflow efficiencies.
