Nickel 18-20%, Chromium 18-22%, Iron balance. Has about 10% less nickel than Incoloy 800. Used in many air heating applications, where it has exhibited superior oxidation resistance at less cost than 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.

Chromium 16-18%, Nickel 11-14%, Iron balance. (316L – Low Carbon) Modified with the addition of Molybdenum (2-3%) to improve corrosion resistance in certain environments, especially those which would tend to cause pitting due to the presence of chlorides. Applications include deionized water. Maximum Sheath Temperature: 1200°F / 649°C

Chromium 18-20%, Nickel 8-11%, Iron balance. (304L – Low Carbon) Used in the food industry, medical, and chemical heating. Maximum Sheath Temperature: 1200°F (649°C)

Chromium 17-20%, Nickel 9-13%, Iron balance. Modified with the addition of Titanium to prevent carbide precipitation and resulting intergranular corrosion that can take place in certain mediums when operating in the 800-1200°F (427-649°C) temperature range.

Standard Copper Alloy A low temperature, inexpensive material used mainly for clean water heating. Maximum Sheath Temperature: 350°F / 177°C

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

Nickel 38-46%, Chromium 19.5-23.5%, Molybdenum 2.5-3.5%, Iron balance Available for a limited number of diameters. Consult Tempco for more information.

A Nickel (30-35%), Chromium (19-23%), 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.

A Chromium (18-20%), Nickel (8-11%), Iron Alloy used in the food industry, sterilizing solutions, air heating and many organic and inorganic chemicals.

A Chromium (18-20%), Nickel (8-11%), Low Carbon Iron Alloy used in the food industry, sterilizing solutions, air heating and many organic and inorganic chemicals.

A Chromium (16-18%), Nickel (11-14%), Low Carbon Iron Alloy with Molybdenum (2-3%) 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.

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.
