GH3030 Plate description
Gnee Steel is a leading manufacturer, supplier, and exporter of GH3030 alloy plates and sheets. We use high-quality raw materials and meticulously manufacture and process our products to meet domestic and international standards. The nickel-chromium alloy in GH3030 plates offers excellent high-temperature oxidation resistance. Furthermore, they exhibit superior resistance to chloride ion stress corrosion cracking, high-purity water corrosion, and acidic environment erosion.
GNEE High Temperature Alloy GH3030 Sheet
GH3030 is a nickel-chromium-based solid solution strengthened superalloy (equivalent to Nimonic 75). It is specifically designed for applications requiring extremely high-temperature oxidation resistance and excellent formability. GH3030 sheet metal can operate at temperatures up to 800°C under structural loads and offers oxidation resistance up to 1000°C, making it ideal for combustion chamber linings and heat-treated fixtures.
Gnee Steel supplies high-quality GH3030 sheet metal, perfectly balancing ductility, weldability, and thermal stability to ensure your components can withstand the most demanding thermal cycling environments.
Gnee Steel offers premium GH3030 alloy steel sheets in a variety of sizes and thicknesses, and provides custom cutting, finishing, and worldwide delivery services to meet your specific project needs.

GH3030 Sheet Manufacturing Process and Quality Control
Our GH3030 sheet manufacturing process ensures fine grains and uniform thickness:
VIM + ESR Melting: Vacuum induction melting followed by electroslag remelting to obtain ultra-clean metal.
Cross-rolling technology: Ensures isotropic mechanical properties (uniform longitudinal and transverse strength).
Strict solution annealing: Controlled heating at 1130°C, followed by rapid quenching to lock in the solid solution state.
Flatness control: Precision leveling ensures the sheet meets the requirements of automated laser cutting machines.

FAQ
Q1: What is the difference between GH3030 and GH3128?
A: GH3030 is a simpler Ni-Cr alloy primarily for oxidation resistance and formability. GH3128 is more complex (with W and Mo), offering higher creep strength at temperatures above 900°C. GH3030 is generally more cost-effective for components under 800°C.
Q2: Can GH3030 plates be used in sulfur-rich environments?
A: Like most high-nickel alloys, GH3030 is susceptible to sulfidation in reducing atmospheres. It performs best in oxidizing or neutral atmospheres. For sulfur-rich environments, please contact our experts for specialized coating or alloy recommendations.
Q3: How do you handle surface protection during shipping?
A: We use PVC film coating for cold-rolled sheets to prevent scratches, and all plates are packed in seaworthy wooden crates with moisture-absorbent silica gel.
Q4: Do you provide a Mill Test Certificate (MTC)?
A: Yes, every shipment includes a full MTC showing chemical analysis, mechanical tests, and grain size inspection according to EN 10204 3.1.
