Incoloy 800 High-Temp rod | Corrosion & Creep Resistant Alloy Solutions
Incoloy 800 Bar Stock: Superior High-Temperature &
Corrosion-Resistant Alloy for Demanding Industries
Incoloy 800 bar stock delivers unmatched performance in extreme
environments, outperforming standard stainless steels (304/316) and
nickel alloys with its triple resistance to oxidation, carburization, and chloride stress corrosion.
Engineered for prolonged thermal stability up to 700°C, this nickel-iron-chromium alloy maintains structural integrity in
sulfuric/phosphoric acid exposure and cyclic heating—critical for
chemical processing, oil refinery valves, and power plant
components. Unlike generic alloys prone to creep deformation,
Incoloy 800 bars offer 30% higher stress-rupture strength under sustained loads, minimizing downtime in tropical climates
common to Southeast Asia. Optimized for ASEAN petrochemical and
Middle Eastern desalination projects, its low lifecycle cost and ASTM B408 compliance ensure reliability in humid, high-salt
environments where 316L stainless steel fails.
