1. Introduction to GH4049 Materials

GH4049 alloy is a Ni-Co-Cr-based precipitation hardened deformation high-temperature alloy, used at below 950 degrees Celsius. This alloy has good oxidation resistance below 1000 degrees Celsius and has a high high temperature strength below 950 degrees Celsius. Compared with nickel-based alloys of similar purposes, the alloy has poor thermal processing plasticity. It can improve its processing plasticity after electroslag remelting or vacuum arc remelting. This alloy is suitable for the manufacture of gas turbine blades with operating temperatures between 850-950°C.
