I. Product Positioning
GH113 is a nickel-based superalloy specifically developed for extreme high-temperature, high-pressure, and corrosive working conditions. With precise composition ratios and advanced smelting technology, it has become a core structural material in aerospace, energy and power, high-end equipment, and other fields, focusing on the dual values of "long-term stable operation + extreme performance breakthrough".
II. Core Features
1. Excellent High-Temperature Resistance
Long-term service temperature up to 1100℃, short-term peak temperature tolerance of 1250℃. It maintains outstanding tensile strength and creep resistance even at high temperatures, solving the industry pain points of material deformation and failure in extreme environments.
2. Superior Corrosion & Oxidation Resistance
Contains multi-component alloying elements such as chromium, tungsten, and molybdenum, forming a dense oxide film that effectively resists high-temperature oxidation, sulfide corrosion, seawater erosion, and other complex media, significantly extending equipment service life.
3. Excellent Processability & Formability
Compatible with various processing methods including forging, rolling, welding, and machining, with high forming precision. It is suitable for manufacturing complex structural components (e.g., blades, combustion chambers, high-temperature pipelines) and meets customized production needs.
4. Stable Mechanical Properties
Minimal fluctuation in mechanical properties across room temperature to high-temperature ranges. With yield strength ≥650MPa and elongation ≥25%, it balances rigidity and toughness, adapting to harsh working conditions such as high-frequency vibration and pressure impact.
