Chromite Ore - an overview ScienceDirect Topics

Because chrome is a very hard metal and has a low coefficient of friction, chrome plating was also used for extending the life of parts that receive heavy wear, such as automobile cylinders, and was useful in boiler pipes to prevent build-up of scale (mineral deposits). Refractory materials are highly resistant to heat and are chemically stable.
