About Incoloy® 800

Incoloy 800 is a nickel-iron-chromium alloy with good strength and excellent resistance to oxidation and carburization in high temperature service. Incoloy 800 is preferred in applications with temperatures upto 100°F. Alloy 800 is primarily used in petrochemical industry for bolting purpose because the alloy doesnt form the embrittling sigma phase after continuous exposures to temperatures as high as 1200°F. Incoloy 800 also has excellent resistance to stress-corrosion cracking in presence of chloride ions. Incoloy 800 is predominently used in bolting pipeline components, instruments and other process equipments in petrochemical industry.
