Chromium(II) carbide - Wikipedia

Chromium(II) carbide is a ceramic compound that exists in several different chemical compositions: Cr 3 C 2, Cr 7 C 3,and Cr 23 C 6. At standard conditions it exists as a gray solid. It is extremely hard and corrosion resistant. It is also a refractory compound, which means that it retains its strength at high temperatures as well.

Chromium Carbides - azom

May 31, 2001  Chromium carbide is used almost exclusively in flux cored wire instead of high carbon ferrochrome as it does not suffer from the dilution effect caused by the extra iron in the high carbon ferrochrome. This means that a coating containing a greater number of hard chromium carbide particles can be produced, which exhibits greater wear resistance.

Chromium Carbide - Welcome to Rio-Carb

When Chromium Carbide (CRC) is manufactured and handled correctly, Chromium (CrC) can last up to eight times longer than traditional materials used in the production of chute liners, which significantly extends the life of the product. It is, therefore, essential to make use of manufacturers that are fully equipped to manufacture genuine quality CrC.

Intergranular corrosion - Wikipedia

Structures made of such steels have to be heated in a whole to about 1065 °C (1950 °F), when the chromium carbide dissolves and niobium carbide forms. The cooling rate after this treatment is not important, as the carbon that would otherwise pose risk of formation of chromium carbide is already sequestered as niobium carbide.
