Incoloy 800 (UNS N08800) nickel alloy forged rings are high-performance heat-resistant alloy components with excellent high-temperature strength, oxidation resistance and corrosion resistance. Fabricated by hot forging and ring rolling processes, these products feature dense microstructure and uniform grain structure. They retain superior mechanical properties and structural stability under high-temperature and corrosive service conditions, making them an ideal choice for petrochemical, heat treatment equipment, power generation and other high-temperature industrial applications.

Manufactured from high-purity ingots via VIM + VAR, this product is formed through upsetting, punching, and seamless ring rolling to ensure optimal tangential grain orientation, significantly enhancing fatigue resistance and structural reliability; the rolled ring is then subjected to solution annealing at 980°C–1040°C followed by rapid water quenching to fully eliminate residual stresses and achieve the standard mechanical properties.
All of our Incoloy 800 forged rings undergo rigorous inspection, including Ultrasonic Testing (UT per ASTM A388), Liquid Penetrant Inspection (LPI), mechanical property verification (per ASTM B564 and ASTM E8/E21), OES chemical analysis, and full dimensional inspection using a Coordinate Measuring Machine (CMM). Each shipment is accompanied by complete Material Test Certificates (MTC) and Non-Destructive Testing (NDT) reports.
