Characteristics
Ferrochrome is a kind of ferroalloy with chromium and iron as main component and it is one of the main alloy agent in iron and steel industry. Ferro chrome contains chromium between 50% and 70%.
Chrome is mainly used to improve the antioxidation and corrosion resistance of steel to make the surface of steel after it is oxidized to form strong adhension oxide film. Then it stops being oxidized or decelerates being oxidized. Micro-carbon ferro chrome is applied to making stainless steel, acid-resistant steel and heat resistant steel.
The Specifications of Ferro Chrome
HCFeCr Cr: 65% min, C: 8.5% max.
Chrome has significant change of steel corrosion resistance and oxidation resistance. And help to improve the wear resistance and high temperature strength. Among various kinds of stainless steel, chromium is an essential ingredient.
Application
Low Carbon Ferrochrome mainly used to produce stainless steel, acid-resistant steel and heat-resistant steel.
