GH3128 nickel alloy plates are premium high-temperature materials engineered for performance in extreme thermal and oxidizing environments. With a thickness range of 10mm to 20mm, these plates are manufactured in accordance with ASTM standards and are ideal for aerospace, petrochemical, thermal processing, and nuclear applications requiring long-term heat and corrosion resistance. GH3128 is a solid-solution strengthened nickel-based alloy known for its excellent structural stability at temperatures up to 1100°C.
High-temperature resistance up to 1100°C
Excellent oxidation and carburization resistance
Complies with ASTM and aerospace specifications
Superior mechanical strength under thermal stress
Good processability: welding, cutting, forming

| 10mm – 20mm | 500mm – 2000mm | 1000mm – 6000mm | ±0.3mm or as per request | Pickled, Hot Rolled, or Machined |
Aerospace: Combustion liners, turbine shields, engine components
Petrochemical: Reforming reactors, cracking tubes, heat treatment trays
Power Generation: Boiler components, steam conduits, high-temp shields
Nuclear Industry: Reactor containment, structural shielding
GH3128 plates are produced according to ASTM specifications and meet strict aerospace material standards such as AMS 5537.
Compared to stainless steel, GH3128 offers significantly better resistance to high-temperature oxidation, carburization, and creep deformation, especially in environments exceeding 1000°C.
Yes, we provide custom cutting, waterjet, plasma cutting, and CNC machining based on customer drawings or specifications.
Yes, full material traceability is provided with MTC (EN 10204 3.1) including chemical composition, mechanical properties, and heat treatment data.
Direct factory pricing with strict quality control
Global export experience with professional logistics
Technical support and material consultation
Flexible MOQ and fast production lead time
