Three gas-fired batch ovens that will be used for hydrogen embrittlement relief of chrome-plated landing gear are on their way to an aerospace parts manufacturer.

The ovens, which were developed by Wisconsin Oven, East Troy, Wis., are stackable so they meet the customer’s production requirements within the space available. Limited floor space did not allow for the batch ovens to be placed side by side.

During the hydrogen-embrittlement-relief process, various parts will be placed on a pallet in the heat-treating oven for periods up to 24 hr. The heating will allow the hydrogen trapped in the chrome plating to be released. Though stacked, the ovens are independently controlled and safely secured. Products arranged on multiple tiers are heated by horizontal airflow.
