Kanthal® Super element grades

Kanthal® Super is a unique material combining the best properties of metallic and ceramic materials. Like metallic materials it has good heat and electrical conductivity and like ceramics it withstands corrosion and oxidation and has low thermal expansion. Maximum temperature 1,700°C (3,090°F).

Kanthal^® Super 1800 is an expansion of the same core characteristics as Kanthal^® Super 1700 with a maximum temperature of 1,800°C (3,270°F).

Kanthal® Super 1900 is an expansion of the same core characteristics as Kanthal® Super 1700 with a maximum temperature of 1,850°C (3,360°F).

Kanthal® Super ER is a new unique concept for heating elements, combining the features of alumina formers with the higher temperature of MoSi2 based heaters. These elements perform well up to 1,580ºC (2,875ºF) in oxidizing, inert and reducing atmospheres.

Kanthal® Super RA is specially designed to work in nitrogen at temperatures above 1,250ºC (2,280ºF). Other Kanthal Super molybdenum disilicide (MoSi2) heating elements have an excellent lifetime in oxidizing atmospheres but, when operating in nitrogen, nitration occurs.

Kanthal^® Super NC is a heating element with special features, designed to meet the demands for clean process heating in the research and electronics industries. Maximum temperature 1,800°C (3,270°F).

Kanthal® Super HT is designed for a longer lifetime of small dimension elements in temperature cycling conditions. The hot strength and form stability is improved. The maximum operating temperature is 1,830°C (3,330°F), and the element is suitable for furnace temperatures between 1,500–1750°C (2,730–3,180°F) approximately.
