GH3030
Early nickel-chromium solid-solution sheet alloy for service up to about 800 C.
Material overview
The High-Temperature Superalloys catalog describes GH3030 as follows: Early nickel-chromium solid-solution sheet alloy for service up to about 800 C. Reviewers should evaluate Good oxidation resistance and stamping/welding performance and simple 80Ni-20Cr chemistry. The grade record lists Combustor components, turbine outer rings, heat shields, and high-temperature sheet parts among typical applications. The dataset currently includes 11 property records covering chemical composition, mechanical properties, and physical properties. Standards and form records reference GB/T 14992 and GB/T 15007 and Sheet / Coil and Bar / Rod. Final supply conditions remain subject to specification, inspection, and export-control review.
