FERRO ALLOYS

MATERIAL DETAILS

Ferro Silicon is a universal “heat-blocker” used in the production of carbon and stainless steels. This additive is used with other ferro alloys in the deoxidising process of steel, as well as in the production of silicon itself. It is also used in the production of cast iron, as it can accelerate graphitisation. Ferro Silicon replaces the need for ferro manganese, spiegeleisen and calcium silicides in the manufacturing process.

Ferro-chrome is added to steel to impart properties of hardness, strength and making it stainless. High Carbon Ferro Chrome is most commonly used in specialist applications such as engineering steels. Low-carbon Ferro-Chrome is used during steel production to correct chrome percentages. It is also a low cost alternative to metallic chrome for uses in super alloys and other special melting applications.

Ferro phosphorus is used mainly as the additives in the foundry industry to improve the floatability of foundry iron, thus improving the quality of the castings. Phosphorus content can increase the wearing resistance and improve the cutability in the castings. Ferro phosphorus also used as the additive in the steel production, which can improve the corrosion resistivity in certain steel products.
