Product Description

Incoloy 800 is a nickel-iron-chromium alloy designed for exceptional strength and metallurgical stability under prolonged high-temperature service. With a nominal composition of 30-35% nickel and 19-23% chromium, this austenitic alloy maintains its microstructure even after extended exposure to elevated temperatures, offering excellent resistance to oxidation, carburization, and corrosion in both high-temperature and aqueous environments.

Unlike standard stainless steels, Incoloy 800 delivers superior creep and rupture strength in the 500°C to 980°C range while also resisting chloride stress corrosion cracking in lower-temperature applications. This dual capability makes it a preferred material for critical components in power generation, petrochemical processing, and heat treatment equipment.

Key advantages:

  • High-Temperature Stability: Remains austenitic and stable after long-term high-temperature exposure

  • Oxidation & Carburization Resistance: Excellent performance in high-temperature atmospheres up to 815°C (1500°F)

  • Creep & Rupture Strength: Superior mechanical properties in the 500-980°C range

  • Chloride Stress Corrosion Cracking Resistance: Outstanding resistance in aqueous environments

  • Versatile Fabricability: Can be formed, welded, and machined using standard techniques
