Manufacturer supply High quality Ferro Chrome
1.Ferro chrome has significant change of steel corrosion resistance and inoxidizability.
2.Ferro chrome can improve the wear resistance and high temperature strength.
3.Ferro chrome provides a wide usage in foundry and steel industry applications.
Chrome is mainly used to improve the antioxidation and corrosion resistance of steel to make the surface of steelafter 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 .
Ferro chrome is a iron alloy which is mainly composed of chromium and iron. It is one of the main alloying agents used in iron and steel industry. Besides chromium and iron, it also contains carbon, silicon, sulfur, phosphorus and other impurities.
Ferro chrome contains 55% ~ 75% chromium, which is divided into high carbon (4% ~ 10% C), medium carbon (0.5% ~ 4% C), low carbon (0.15% ~ 0.5% C) and micro carbon (max 0.15% C).

1.LcFeCr mainly used to produce stainless steel, acid-resistant steel and heat-resistant steel.
2. It mainly used as steel making alloying additives, used in steel making refining later joined.
3.FeCr can used as alloy agent to improve the hardenability of steel and increase the wear resistance and hardness of steel.
4.It used as the additive of cast iron to improve the abrasion resistance and hardness of cast iron.
