  • SOME ASPECTS OF THE PRODUCTION OF FERROCHROME

    In the conventional production of stainless steels, chromium is generally introduced to the process in the form of Cr-Fe-C-Si alloys, principally as high-carbon ferrochrome or charge chrome. The level of carbon and silicon in the above alloys is important especially when refining is carried out by blowing oxygen in the melt.

  • Chrome plating - Wikipedia

    Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. The after product of chrome plating is called chrome.The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes.
