Product Description
GH3044 is a solid solution strengthened nickel-based superalloy, specially designed for extreme high-temperature environments. It exhibits excellent comprehensive performance below 900℃. Its main characteristics and applications are as follows:
Core Characteristics
Excellent High-Temperature Performance
Oxidation Resistance Containing 23.5%–26.5% chromium, a dense Cr₂O₃ oxide film is formed at high temperatures, enabling long-term resistance to oxidation environments at 816℃, and intermittent use temperatures up to 982℃ Mechanical Properties With room temperature tensile strength ≥685 MPa, yield strength ≥270 MPa; it still maintains moderate hot strength at 900℃, and exhibits outstanding creep resistance Plastic Workability Elongation ≥40%, cold stamping deep drawing coefficient K limit = 2.06, suitable for complex part forming Physical Properties
Density 8.89 g/cm³ Melting Point 1352–1375℃ Thermal Properties
Coefficient of thermal expansion (20–100℃) 12.25×10⁻⁶/℃ Thermal conductivity (100℃) 11.7 W/(m·K) Process Characteristics
Cold-rolled plate process: Precision cold rolling tolerance control ±0.02mm, intermediate annealing is required to restore plasticity.
Welding Performance
Supports TIG welding, spot welding, and seam welding. GH2132 welding wire is recommended, and interlayer temperature must be strictly controlled to prevent cracking.
Application Fields
● Aerospace, aero-engine combustion chamber flame tubes, afterburner casings and heat shields, resistant to 900℃ hot gas erosion.
● Rocket nozzles, spacecraft thermal protection components.
● Energy and industry, gas turbine transition sections, nuclear power heat exchanger pipelines.
● Chemical cracking furnace tubes, high-temperature reactor linings (resistant to sulfur/chloride corrosion).
Technical Specifications
● China GJB 2612-1996 Cold-drawn wire for welding
● International ASTM B637 (US standard) Plate/tube performance
● Testing requirements Eddy current testing, high-temperature durability test (GB/T 2039)
Precautions
● Narrow hot working window: Forging final forging temperature ≥900℃, avoid abnormal grain growth.
● Welding sensitivity: Strict preheating and post-weld stress relief treatment are required to prevent embrittlement of the heat affected zone.
● Performance comparison: Compared with similar nickel-based alloys (such as GH3039), GH3044, due to its high tungsten content (13–16%), has improved creep resistance by about 30% above 800℃.
The company currently owns production equipment such as vacuum melting, electroslag remelting, forging and hot rolling (outsourced), solution treatment, machining, cold drawing, cold rolling (outsourced), and polishing. Our own laboratory can complete the testing of alloy chemical composition, mechanical properties, and flaw detection.
We can independently produce high-performance alloy materials such as nickel-based superalloys, cobalt-based superalloys, precision alloys, and special stainless steels. Products: forgings, billets, coils, bars, slabs/sheets, etc.
