Jet Engine Components GH2903/GH903/N09903/Incoloy903 High Temperature Alloy Nut With Top Performance

The GH2903 (GH903/N09903/Incoloy 903) high-temperature alloy nut is a specialized fastener made from a nickel-iron-cobalt-based superalloy. It is designed for applications requiring high strength, excellent oxidation resistance, and thermal stability in temperatures up to 650°C (1202°F). This alloy offers exceptional resistance to stress relaxation and thermal expansion, making it ideal for aerospace, gas turbines, and high-performance engineering applications.

GH2903 nuts exhibit good corrosion resistance in harsh environments and retain their mechanical properties under cyclic thermal stresses. The alloy is precipitation-hardened for enhanced strength and creep resistance, ensuring long-term performance in demanding conditions. These properties make it a preferred choice for jet engines, power plants, and critical fastening solutions where reliability under extreme heat and mechanical loads is crucial. Common standards and specifications for GH2903 nuts include AMS 5991, ASTM B637, and GB/T 14992. These ensure consistent quality and performance across industries requiring high-temperature fastening solutions.

GH2903/GH903/N09903/Incoloy903 Alloy Nut Key Features:

GH2903 (also known as GH903, N09903, or Incoloy 903) is a high-temperature alloy known for its excellent mechanical and thermal properties. Here are the key features of nuts made from this alloy:
