GH3030 Plate description
GNEE GH3030 Alloy Plate
GH3030 sheet is a titanium-stabilized nickel-chromium-based solid solution strengthened superalloy. Globally recognized as an equivalent to Nimonic 75 (Alloy 75), it is the material of choice for engineers designing components that must withstand extreme temperatures and offer excellent machinability.
GH3030 alloy sheet possesses a stable microstructure and excellent oxidation resistance. It maintains its integrity at operating temperatures up to 800°C (1472°F) and resists oxidation at temperatures up to 1000°C (1832°F).
Gnee Steel, an ISO-certified professional supplier of GH3030 sheet, offers high-quality sheet that perfectly balances ductility, thermal fatigue resistance, and weldability.

About Gnee Steel
Ultra-Clean Melting: We use Vacuum Induction Melting (VIM) + Electroslag Remelting (ESR) processes to remove impurities, ensuring excellent thermal fatigue life.
Excellent Cold Formability: Our steel sheets undergo special annealing treatment, resulting in high plasticity, making them ideal for complex stamping, deep drawing, and spinning processes.
Weldability: GH3030 is arguably the easiest high-temperature alloy to weld (TIG welding, MIG welding, spot welding, seam welding), with weld efficiency almost equivalent to the base material.
Full Traceability: Each steel sheet comes with a Material Inspection Certificate (MTC) conforming to EN 10204 3.1, directly linked to the heat number.

FAQ
Q1: Can GH3030 plates be used in sulfur-containing environments?
A: Like most high-nickel alloys, GH3030 is sensitive to sulfidation in reducing atmospheres. It is best suited for oxidizing or neutral atmospheres. For sulfur-rich environments, please consult our engineers for specific coating or alloy alternatives.
Q2: What is the recommended heat treatment for GH3030 after cold forming?
A: We recommend a Solution Treatment at 1100°C - 1150°C followed by rapid air cooling or water quenching to restore ductility and optimal oxidation resistance.
Q3: How do your GH3030 plates compare to 310S Stainless Steel?
A: GH3030 is a nickel-based superalloy, whereas 310S is a high-alloy stainless steel. GH3030 has significantly better creep strength and does not suffer from the "sigma phase" embrittlement that can make 310S brittle after long-term service at 800°C.
Q4: Do you offer PVC coating for cold-rolled sheets?
A: Yes, we can apply single or double-sided PVC protective film to ensure your sheets arrive without a single scratch on the bright finish.
