Flanged Immersion Heaters – Sheath Materials

Incoloy 800

Nickel 30-35%, Chromium 19-23%, Iron balance.

The high nickel content of this alloy contributes to its resistance to scaling and corrosion. Used in air heating and immersion
heating of potable water and other liquids.

Copper

Standard Copper Alloy

A low temperature, inexpensive material used mainly for clean water heating.

Maximum Sheath Temperature: 350°F / 177°C

Steel

Low Carbon

Used for high to low viscosity oils, asphalt, tar, wax, molten salt, heat transfer liquid media and other compatible solutions.
