“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 Silico Manganese is used as a deoxidizer and an alloying element in steel.
It can be used as a substitute for Ferro Silicon and Ferro Manganese when added to make different types of steel.”

“Ferro-manganese is used mainly in the steel industry for hardening and desulphurisation of steel and as a deoxidizer,
making the slag more fluid.”

“Ferro-chrome is added to steel to impart properties of hardness, strength and to make 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.”

Packing: 1 MT big-bag

“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 is also used as additive in the steel production, which can improve the corrosion resistivity in certain steel products.”

Ferro Sulphur

Grade	S (%)	Si (%) max	Al (%) max	Moisture (%) max
FeS	50–52 %	2 % max	0.8 % max	0.5 % max

Size: 3–10 mm / 10–50 mm

Packing: 25 kg bags in 1 MT big-bag on pallet

“Ferro Sulphur is used in metallurgy to give the steel or alloy the desired sulphur content.
It is used for this purpose instead of elemental sulphur because the low melting point of the sulphur could accumulate on the molten metal surface,
causing SO₂ emissions and also a deterioration of its mechanical properties by the formation of a low eutectic melting point in the grain boundaries.”
