Nickel Alloy Forged Ring with High-strength, Highly Corrosion-resistant Core Industrial Component

Inconel 625 (UNS N06625): Excellent high-temperature and corrosion resistance, used in chemical equipment and offshore platforms.

Inconel 718 (UNS N07718): Precipitation-hardening alloy with high strength and fatigue resistance, commonly used in aero-engine ring components.

Inconel 600 / 601 (UNS N06600 / N06601): Resistant to oxidation and carbonization, suitable for heat treatment furnaces and exhaust systems.

Hastelloy C-22 / C-276 (UNS N06022 / N10276): Resistant to strong acids and chloride ion corrosion, used in chemical and pharmaceutical fields.

Monel 400 / K-500 (UNS N04400 / N05500): Resistant to seawater corrosion, used in marine and pump/valve systems.

Incoloy 800 / 825 (UNS N08800 / N08825): Used in petrochemical equipment and heat exchangers, with stable oxidation resistance.

Manufacturing Process

Forging Stage: Vacuum smelting or electroslag remelting ingots are used, followed by upsetting, punching, ring expansion, and ring rolling.

Heat Treatment: Solution treatment or aging treatment to improve grain structure and enhance toughness and corrosion resistance.

Machining: CNC lathe finishing to ensure dimensional accuracy and roundness.

Surface Treatment: Polishing to a metallic luster to reduce stress concentration and improve corrosion resistance.

Inspection and Testing: 100% ultrasonic testing (UT), penetrant testing (PT), dimensional and surface roughness inspection.

Performance Advantages

High Temperature Strength: Stable tensile and creep properties at 700–1000°C.

Excellent Corrosion Resistance: Resistant to acid, alkali, chloride, and oxidizing media.

Dense Microstructure: Ring rolling process ensures fine grains and no shrinkage cavities or cracks.

Long Life and Stability: Suitable for long-term high-pressure, high-temperature cyclic conditions.
