  • Patent number: 4227874
    Abstract: A heat resistant, structurally stable member is provided for in high temperature, heat treatment processing. It includes a core which has a high melting point higher than the processing temperature but which crystallizes, and so becomes frangible, at temperatures lower than the processing temperature. It is encased in a covering of a weldable, non-crystallizing alloy which may begin to soften at lower than processing temperatures, but is thick enough to be welded and to prevent loss of strength of the core due to crystalline shattering. Consequently, this structural member retains rigidity during high temperature usage.A plurality of structural members are welded together to form racks or baskets for holding parts during heat treatment in high temperature processing.
