FAQ
GH2747 wire is a wire-form product made to the GH2747 heat-resistant alloy grade, also known as GH747. Confirm the exact grade, specification and chemical analysis against the documents for the supplied material.
GH747 is a designation associated with GH2747 in available grade references. State the exact designation and standard required in your purchase specification, and confirm it against the supplier’s material documents.
This page describes GH2747 heat-resistant alloy wire, not a qualified resistance-heating element. Do not select it as heater wire based only on its heat resistance. For an energized heating application, request verified electrical resistivity and operating data for the required wire size and design.
A single maximum temperature cannot be confirmed from the alloy name alone. The allowable temperature depends on the specification, material condition, atmosphere, load and component design. Provide your service conditions so the appropriate data can be checked.
