Product name :Ferrous Sulphide / Iron Sulphide
Description:
Ferro Sulphur is a Ferro Alloy composed of iron and sulphur with a sulphur content ranging between 28% and 32%, with this content being what defines the quality of the product.
There are typically two grades according to its sulphur content, between 28%and 32% and between 48% and 50%, as a by-product of the steelmaking process.

It is stable under normal pressure and temperature conditions.
However, it should be kept away from heat and ignition sources.
Empty containers may present a risk of fire.
Contact with moisture, acids and strong oxidizers should be avoided, as well as from flammable materials.
It is not classified as a hazardous good for transportation.

Application :
Ferro Sulphur is used in metallurgy 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 onthe molten metal surface,causing SO2 emissions and also a deterioration of its mechanical
propertiesby the formation of a low eutectic melting point in the grain boundaries.
For these purposes it is used in:
The manufacturing of cast iron:
When melted in foundries, the level of residual sulphur is reduced, primarily due to the use of scrap steel
and low sulphur content. It has been determined that melting does not respond easily to inoculants if the
sulphur level is less than 0.04%.
Therefore, it is necessary to raise the sulphur content using Ferro Sulphur to maintain the level in a range
from 0.05%-0.12%.
The manufacturing of alloyed steels:
Used as a suitable and economical resulphurizing agent
to prevent hydrogen embrittlement and to maintain minimum sulphur content of no less than 0.015%.
Cutting steel manufacturing:
It is used as a resulphurizing agent
in the manufacture of this type of steel because it increases machinability.
Electric furnaces:
It has a positive effect,
maintaining sulphur content around 0.15% since it enhances the nodular iron formation.
