Incoloy 800 UNS N08800 Nickel Alloy Forged Round Bar, Conforming to ASTM B408 Standard, High-Temperature Corrosion Resistant, for Petrochemical Applications

Incoloy 800 Nickel Alloy Forged Round Bar

Incoloy 800 (UNS N08800 / W.Nr. 1.4876) nickel alloy forged round bar is a high-performance nickel-iron-chromium alloy material with excellent high-temperature strength, corrosion resistance, and oxidation resistance. Thanks to its outstanding high-temperature stability and excellent forged microstructure, it is widely used in petrochemical, heat treatment, power generation, nuclear industry, and high-temperature industrial equipment. It is one of the most commonly used heat-resistant alloy materials under high-temperature service conditions.

Key Features

• Excellent high-temperature strength: Maintains good mechanical properties in the temperature range of 600°C – 800°C.
• Outstanding oxidation resistance: Forms a dense and stable oxide layer in high-temperature air environments, preventing further oxidation.
• Good resistance to carburization: Suitable for severe environments such as cracking furnaces and heat treatment furnaces.
• Excellent corrosion resistance: Provides strong resistance to various chemical media and high-temperature gases.
• Stable austenitic microstructure: Resistant to embrittlement during long-term high-temperature service.
• Good weldability: Suitable for TIG, MIG, and manual arc welding processes.
