A whte to silver metallic material which is very hard and brittle. Chromium is chemically very resistant. There is little Oxidation in the air. It can be solved by not oxidizing acids like HCL, reacting to chromium salts.

Chromium coatings protect very well from oxidation and provide docerative appearance. Chromium coatings can be deposited by galvanic techniques what requires electrical conductivity of the substrates or by CVD.

Chrome alloy steel is characterized by high strength, thermal and corrosive stability.
