GH3039 Alloy Description
Gnee Alloy GH3039 Nickel-Based Solid Solution Superalloy Description
GH3039 is a single-phase austenitic, solid-solution strengthened nickel-based superalloy (non-precipitation hardening type). It relies solely on solid-solution strengthening to achieve long-term microstructural stability at high temperatures. With nickel as the matrix, the alloy utilizes chromium (approx. 19.0–22.0%) for oxidation and corrosion resistance, while molybdenum (approx. 1.8–2.3%) and niobium (approx. 0.4–0.9%) serve as solid-solution strengthening elements; it also contains iron (≤3.0%) and titanium (0.30–0.60%).
Regarding its service temperature range, the alloy maintains moderate thermal strength below 850°C and exhibits excellent oxidation resistance during long-term use at temperatures up to 1000°C. It possesses excellent cold-forming and welding capabilities and can be processed into forms such as sheets, bars, wires, tubes, and forgings. Furthermore, surface treatments-including laser shock peening (LSP), boron-chromium co-diffusion, or aluminizing-can be applied to further enhance fatigue life, surface hardness, and oxidation resistance.

Why Global Buyers Prefer GH3039 Over GH3044/GH4169
Superior Cold-Forming Performance (Key Procurement Advantage)
Actual procurement data from over 300 manufacturers shows that, under identical stamping processes, GH3039 yields a 40% lower scrap rate than GH3044, significantly reducing production waste costs for customers during large-scale sheet metal component fabrication.
Optimal Balance of Cost and Intermediate-Temperature Performance
For equipment operating stably between 800°C and 1000°C, GH3039 offers a unit price 12%–18% lower than GH3044 while maintaining excellent oxidation and thermal fatigue resistance, making it the most cost-effective choice for large-scale industrial applications involving intermediate-temperature components.
Outstanding Thermal Cycling Fatigue Resistance
For industrial furnace and gas turbine components subject to frequent thermal cycling, GH3039 offers double the service life of standard nickel-based alloys, effectively reducing equipment replacement frequency and after-sales maintenance costs.
Ease of Welding and Post-Processing
It exhibits a low tendency for weld cracking and is compatible with standard TIG (Tungsten Inert Gas) welding processes used by global equipment manufacturers; unlike age-hardening alloys such as GH4169, it requires no specialized welding parameter adjustments.

FAQ
Q1: What core property makes GH3039 stand out from other GH series high temp alloys? What is its stable working temperature range?
A: GH3039 is a single-phase austenite solid-solution nickel alloy optimized for 800℃–1000℃ cyclic thermal environments. Its biggest competitive advantage is outstanding thermal cycle fatigue resistance + superior cold stamping ductility. Compared with GH3044, GH3039 has 40% lower stamping scrap rate for mass liner production, with 12%-18% lower unit cost for medium-temperature working scenarios.
Long-term continuous stable service temperature: 800℃ ~ 1000℃
Short-term peak temperature tolerance: Up to 1050℃ It cannot be hardened by aging heat treatment; only single solution annealing is required for final performance.
Q2: What product forms of GH3039 can you supply? What dimensional ranges are in regular stock?
A: We fully produce 3 core finished forms for global export, all with standard inventory sizes for fast MRO delivery:

Q3: What's the difference between GH3039 and GH3044? How do I choose the right grade for my project?
A: Summarized from 20 years of procurement data, clear selection criteria for engineers & buyers:
GH3044
Max oxidation resistance up to 1200℃, higher tungsten content for ultra-high static temperature anti-oxidation
Poor cold forming performance, high stamping scrap rate, higher raw material cost
Best for static ultra-high temp shielding parts working above 1000℃ with low mechanical load
GH3039
Balanced performance for 800–1000℃ cyclic heating & cooling environments
Excellent cold stamping, bending & welding performance, low production scrap loss
Superior thermal cycle fatigue life for furnace, afterburner components with frequent temperature fluctuation
More cost-effective for mass medium-temperature production Selection Rule: If your equipment runs below 1000℃ with repeated heating cycles and needs stamping forming → Choose GH3039; If stable static service above 1050℃ with zero complex forming → Choose GH3044.
Q4: What two melting processes do you offer for GH3039? What's the difference for export audit?
A: We provide two melting grades matching different customer budgets & industry audit standards:
Industrial Grade (Single VIM Melting) Suitable for ordinary industrial furnace, petrochemical non-critical parts, cost-saving option, basic UT inspection provided.
Aviation MRO Grade (VIM+ESR Double Vacuum Melting) Mandatory for aerospace afterburner, gas turbine hot-section components. Eliminates element segregation, micro-shrinkage and harmful impurities (S/P locked below standard limit). Comes with 100% UT+MT full NDT inspection, Class A internal flaw report, meets global aviation supplier audit requirements, complete dual-use material export documents available for Kazakhstan, CIS, EU aerospace clients.
Q5: What surface finish of GH3039 sheet is most popular for global export orders?
A: The 2B cold rolled annealed & pickled matte finish accounts for 70% of our overseas bulk orders. It balances cost, stamping performance and weldability, ideal for furnace liners, aircraft afterburner shielding plates mass production. Other surface options for special demands:
BA Bright Annealed: Mirror oxide-free high-cleanliness surface, for semiconductor thermal equipment & aerospace sealing thin sheets
No.1 Hot Rolled Pickled Plate: For heavy furnace lining over 4mm thickness, low surface precision demand
Sand Blasted: Used as base material for thermal barrier coating (TBC) on gas turbine parts.
