Discover the latest trends and innovations in the nickel alloy industry. We provide expert insights and in-depth analysis on the newest developments in nickel alloys.
Shanghai COCESS Special Alloy Co., Ltd., as a professional supplier in the field of special alloy materials, deeply understands the specific requirements of different applications for material forms and specifications. For GH4169, known as the "ace alloy" in aerospace, energy, and chemical industries, we are committed to building a comprehensive product matrix. We can stably supply forgings, plates, and bars in various forms with complete specifications. Our aim is to provide you with a one-stop, highly compatible material solution for your design, R&D, and manufacturing, helping you flexibly address challenges ranging from core load-bearing components to complex structural parts.
GH4169 is a precipitation-hardened nickel-based superalloy independently developed in China, with performance equivalent to the American Inconel 718. Its outstanding comprehensive capabilities make it one of the most widely used superalloys. Its core advantages are reflected in:
Ultra-High Strength and Excellent Fatigue Performance: Through the combined precipitation strengthening of γ″ [Ni₃Nb] and γ′ [Ni₃(Al,Ti)] phases, it exhibits extremely high yield strength, tensile strength, and excellent fatigue resistance in the temperature range of -253°C to 650°C, making it an ideal choice for manufacturing high-load components.
Excellent Weldability and Formability: Compared to other precipitation-hardened alloys of similar strength grades, GH4169 has excellent welding performance, is crack-free after welding, and offers good cold and hot workability, facilitating the manufacturing of complex components.
Good Corrosion Resistance and Radiation Resistance: It is corrosion-resistant in various media and possesses certain resistance to neutron irradiation damage, making it suitable for diverse environments.
Core Application Areas: Aero-engine turbine disks, compressor disks, blades, casings; Aerospace structural parts, fasteners; Energy sector gas turbine disks, pump and valve parts, nuclear reactor components, etc.
By integrating upstream core resources, we ensure stable quality and a wide range of specifications for GH4169 materials, meeting your needs throughout the entire chain from blanks to finished products.
GH4169 Forgings
Product Range: We can provide open-die forgings, closed-die forgings, and ring-rolled products. Suitable for manufacturing key load-bearing structural parts such as turbine disks, compressor disks, flanges, valve bodies, and high-pressure shells.
Process Advantage: By controlling forging processes (such as isothermal forging, multi-directional forging), a uniform and refined grain structure is obtained, ensuring the material has excellent through-thickness properties, fatigue strength, and crack propagation resistance.
Specification Capability: Forgings ranging from a few kilograms to several tons can be provided according to drawings, meeting requirements for different sizes and shapes.
GH4169 Plates/Sheets
Product Range: We supply hot-rolled medium and heavy plates, thin sheets, and cold-rolled strips. They are ideal materials for manufacturing casing shells, seal rings, heat exchanger plates, structural liners, etc.
Complete Specifications: A wide range of thicknesses is available (e.g., thin sheets from a fraction of a millimeter to several millimeters, medium/heavy plates up to several tens of millimeters), widths can be customized according to demand, meeting blanking needs for different structural parts.
Various Conditions: Can be supplied in different heat treatment conditions such as solution-treated, aged, as well as various surface finish conditions.
GH4169 Bars/Rods
Product Range: We supply hot-rolled bars, forged bars, cold-drawn bars, and bright bars. Mainly used for manufacturing shafts, bolts, fasteners, blade blanks, mold core rods, etc.
Rich Specifications: Round bar diameters range from Φ10mm to over Φ300mm, with large-diameter forged bars available. Square steel, hexagonal steel, and other special-shaped bars are also supplied.
High-Performance Option: We specially provide GH4169 superalloy wire for high-performance fasteners, meeting high standards such as AMS and GB.
We not only provide products with complete specifications but also ensure that each batch of material has reliable quality and complete delivery guarantees.
Full-Process Quality Control: From raw material smelting (VIM+VAR/ESR process), forging/rolling to final heat treatment, the entire process follows strict specifications. Materials comply with advanced domestic and international standards such as GB/T 14992, GJB 2611, AMS 5662/5663.
Complete Quality Documentation: Each batch of material is accompanied by the original manufacturer's Material Test Certificate (MTC), detailing chemical composition, mechanical properties (room temperature and high temperature), ultrasonic testing results, etc., ensuring full traceability.
Professional Technical Service: Our team can provide customers with technical support regarding GH4169 material properties, heat treatment systems (solution + double aging), machining and welding recommendations, assisting you in optimizing material selection and manufacturing processes.
Choosing us means you will gain the following value:
One-Stop Procurement Convenience: No need to find multiple suppliers for forgings, plates, and bars separately, greatly simplifying your supply chain management and improving procurement efficiency.
Accurate Specification Matching: Rich specification reserves and customization capabilities ensure you obtain the required material in the most economical size and form, reducing waste and optimizing costs.
Stable and Consistent Quality: All forms of materials originate from the same strict quality management system, ensuring performance stability and batch-to-batch consistency, safeguarding the reliability of your final product.
Rapid and Flexible Response: We maintain stock of commonly used specifications and can quickly coordinate production based on your urgent needs, providing flexible delivery solutions.
