Chromel®-A
Maximum Temperature:
Element: 2250 F.
Operating: 2150 F. |
Excellent ductility, weldablility, hot strength and mechanical stability. Highly resistant to oxidation and most forms of corrosion at elevated operating temperatures. |
Appliance and furnace heating elements operating in clean, dry air. May also be used in vacuum and completely inert or strongly reducing atmospheres. |
Chromel®-AA
Maximum Temperature:
Element: 2250 F.
Operating: 2150 F. |
Exceptionally resistant to oxidation, green rot corrosion, carburization, and sulfur contamination. Mechanical properties are similar to those of Chromel®-A. |
Developed primarily for use in controlled atmosphere furnaces and applications involving metallic contaminants. Also in vacuum furnaces and appliances. |
Chromel®-C
Maximum Temperature:
Element: 1950 F.
Operating: 1850 F. |
Has very good room and high temperature mechanical properties-plus excellent resistance to oxidation and corrosion in the medium high temperature range. |
Widely used in domestic appliances and various small heating devices requiring elements capable of providing very high resistance's within a limited space. |
Chromel®-D
Maximum Temperature:
Element: 1900 F.
Operating: 1800 F. |
Highly resistant to oxidation, green rot as corrosion and sulfur attack in the medium high temperature range. Has good hot strength and mechanical stability. |
Commonly used as heating elements in controlled atmosphere furnaces that are operated in the critical temperature range between 1500 and 1900 F. |
