ZYTC Alloy Expands Global Reach: GH2036 Round Bar Exported to Poland Under Strict GB/T Standards
GH2036High-Temperature Alloy: Precision Engineering for Demanding Applications
Introduction
GH2036 (also designated as GH36) is a Fe-Ni-Cr-based precipitation-hardening deformed high-temperature alloy, renowned for its excellent mechanical properties and stability in extreme environments. Operating effectively at temperatures up to 650°C, it leverages vanadium carbide (VC) precipitates for strengthening, ensuring reliability in high-stress applications like aerospace turbines and power generation systems. ZYTC Alloy recently delivered GH2036 round Bars (ø20⁻⁰/₋₀.₀₅₂ × 2000 mm) to Poland, manufactured under China’s rigorous GB/T 14994 standard. This shipment highlights our commitment to global quality benchmarks, including ASTM, EN, and AMS.
GH2036 Chemical Composition: Balanced for Strength and Stability
GH2036’s composition optimizes high-temperature performance and corrosion resistance:
-
Base Elements: Iron (Fe, balance), Nickel (Ni, 7-9%), Chromium (Cr, 11.5-13.5%)
-
Strengtheners: Vanadium (V, 1.25-1.55%), Molybdenum (Mo, 1.1-1.4%), Niobium (Nb, 0.25-0.55%)
-
Carbon & Stabilizers: Carbon (C, 0.34-0.40%), Manganese (Mn, 7.5-9.5%), Silicon (Si, 0.3-0.8%)
-
Impurity Control: Phosphorus (P ≤ 0.035%), Sulfur (S ≤ 0.030%)
The high Cr content forms a protective Cr₂O₃ oxide layer, while Mo enhances corrosion resistance in acidic or sulfidic environments.
GH2036 Mechanical Properties: Engineered for Extreme Conditions
GH2036 excels in high-temperature strength and workability:
-
Tensile Strength: ≥830 MPa
-
Yield Strength: ≥600 MPa
-
Elongation: ≥15%
-
Hardness: 3.45–3.65 HB (measured by indentation diameter)
-
Physical Properties:
-
Density: 7.85 g/cm³
-
Thermal Expansion Coefficient (20–700°C): 23.13 × 10⁻⁶/K
-
Thermal Conductivity: 14.2 W/(m·K)
-
Heat treatment—including solution treatment (1140°C, water-cooled) and two-stage aging (670°C + 770–800°C)—enhances fatigue life by 109% and hardness by 17.3%.
GH2036 Applications: Powering Critical Industries
GH2036’s blend of machinability and thermal stability makes it ideal for:
-
Aerospace: Turbine disks, compressor rings, and fasteners in jet engines.
-
Energy: Gas/diesel-engine turbocharger blades and nuclear reactor components.
-
Industrial: High-pressure valves, reactor vessels, and heat exchangers.
Note: Long-term use above 650°C may induce grain coarsening or intergranular corrosion. ZYTC Alloy mitigates this through controlled processing to minimize defects like cracks.
ZYTC Alloy’s Manufacturing Excellence
Our recent delivery of GB/T 14994-compliant round bars to Poland exemplifies our capabilities:
-
Product Range: Bars, sheets, strips, wires, seamless/capillary tubes, and forgings.
-
Quality Assurance: Ultrasonic testing (per GB/T 4162 Grade A), heat-treatment validation (NADCAP-certified), and dimensional precision (e.g., ±0.05 mm for tubes).
-
Global Standards: Compliance with ASTM (US), EN (EU), and AMS (aerospace) specifications.
-
Efficiency: Fast delivery, competitive pricing, and full traceability from melt (VIM/ESR) to finish.
Conclusion
GH2036 remains a cost-effective solution for sub-650°C applications requiring robust mechanical and anti-oxidation properties. ZYTC Alloy combines advanced metallurgy with stringent quality control to serve global clients in aerospace, energy, and heavy industry.
