Chromium

There are many different types of chrome used in the metal casting industry. We supply high carbon ferrochrome, various low carbon ferrochrome, and aluminothermic chrome. The kind of chrome used for metal casting is very dependent on the grade of metal you are attempting to produce.

Chrome is added to steel for its corrosion resistance, improved hardenability, wear resistance, and high-temperature strengths. When chrome is added to iron, you create chrome carbides that are very abrasion-resistant. Superalloy producers will use aluminothermic chrome or pure chrome because they have a grade that has no iron or extremely low iron tolerances.

Low Carbon FeCr consist of .1, .05, .025, .015 carbon content. High carbon FeCr is anywhere from six to eight percent carbon.
