New Materials for Fabricated Gas Turbine Hot Section Components

Abstract

Materials have been developed in recent years which are particularly well‐suited for use in fabricated gas turbine hot section components. Among these are HAYNES® alloy No. 230 and HASTELLOY® alloy S. These alloys combine very good performance characteristics with capability for fabrication into such complex components as combustion chambers, afterburner flame‐holders, seal rings, and thermocouple/probe assemblies. The properties and fabrication characteristics of these two materials are reviewed and compared with other well‐known gas turbine alloys.
