    Fabrication and Heat Treatment

    Machinability

    HAYNES 214 can be machined using the common processes used for iron based alloys. The material work-hardens during machining and has higher strength and gumminess. It is recommended that heavy duty machining equipment and tooling be used. Commonly available commercial coolants can be used for the process.

    Forming

    HAYNES 214 has good ductility and hence can be readily formed using all the common methods. It is recommended that powerful equipment be used for forming as this alloy is stronger than regular steel.

    Welding

    Welding of HAYNES 214 can be performed using all the traditional welding methods except for submerged-arc welding. It is recommended that a matching alloy filler metal be used.

    Annealing

    Annealing of this material can be performed at 1093°C (2000°F) and then rapidly air cooled.

    Cold Working

    Cold working can be performed with the use of standard tooling except for plain carbon tool steels, which produces galling.

    Applications

    HAYNES 214 is used in the following application areas:

    • Industrial furnace parts
    • Gas turbine components
    • Gas fired radiant heating tubes
    • Refractory anchors
    • Furnace flame hoods
    • Combustor splash plates
