Introduction
Incoloy 840 (Alloy 840, 1.4847, UNS S33400) nickel-based alloy tube and pipe
Incoloy 840 is a nickel based alloy, it's also an austenitic stainless steel containing titanium and aluminum, it contains enough chromium to form and maintain a sufficient scale of chromium oxides to protect it under high temperature conditions, it has more resistant to high temperatures abilities than traditional stainless steels such as SS304, so it is suitable for the shell tube of advanced electric heater. Benefit from higher nickel content, Incoloy 840 has better oxidation resistance than the standard chromium-nickel stainless. Its oxidation resistance is comparable to higher grade alloys used at temperatures up to 1900°F (1038°C).

Incoloy 840 heating elements features:
Widely used burn-in-air heating.
High resistance against moist environments.
Recommended for users who do not need very high corrosion resistance.
Limit service temperature(UL) : 880°C or less
Incoloy 840 tube heating elements application:
Because of its formability, weldability, corrosion resistance and oxidation resistance, Incoloy 840 is a common material which is widely used for electric heaters, heat exchangers, equipment heaters, industrial heaters and other equipment, and is also commonly used in automotive exhaust systems.
