Standard Element Sheath Materials
|
| • |
Incoloy® 800 — A Nickel (30 to 35%), Chromium (19 to 23%), Iron alloy. The high nickel content of this alloy contributes to its resistance to scaling and corrosion. Used in air heating (also see Incoloy® 840) and immersion heating of potable water and other liquids that are not corrosive to an Incoloy® 800 sheath.
|
| • |
Low Carbon Steel — Applications include fluid heat transfer media, tar, high to low viscosity petroleum oils, asphalt, wax, molten salt, and other solutions not corrosive to a steel sheath.
|
| • |
316 Stainless Steel — A Chromium (16 to 18%), Nickel (11 to 14%), Iron Alloy with Molybdenum (2 to 3%) added to improve corrosion resistance in certain environments, especially those that would tend to cause pitting due to the presence of chlorides. Applications include deionized water.
|
| • |
Copper — Mainly used in clean water heating for washrooms, showers, rinse tanks and freeze protection of storage tanks.

Surface Treatments for Stainless Steel and Incoloy® Elements and Other Wetted Parts to Improve Corrosion Resistance
Flanged immersion heater surfaces in contact with the material being heated can be passivated or electro-polished to improve
their resistance to corrosion.
Passivation removes surface contamination, usually iron, so that the optimum corrosion resistance of the stainless steel
is maintained. Surface contamination would come from the small amount of steel that may be worn off a tool during the
manufacturing process. Passivating is accomplished by dipping the heater in a warm solution of nitric acid.
Electro-Polishing is an electrochemical process that removes surface imperfections and contaminants, enhancing the corrosion
resisting ability of the stainless steels. The resultant surface is clean, smooth and bright. Many medical and food applications
require this finish.
8 watts/in2 (1.3 watts/cm2)—Typical Applications: Fuel Oils (Bunker C and Number 6)
Note: 3-Phase only. Cannot be rewired for single phase.
