is an additive in steel smelting and is commonly used in the casting of some special steels. Ferrosilicon nitride has good high-temperature resistance and is also a very common raw material in the configuration of anhydrous gun clay. The addition of ferrosilicon nitride not only supplements the required nitrogen source for the molten steel, but the silicon in it can also react with the oxygen in the molten steel to remove excess oxygen. The addition of silicon can also bring benefits to the steel. Some improvement. Let's take a look at the impact of the addition of ferrosilicon nitride on steel quality.

Since nitride precipitates on the grain boundaries, it can improve the high-temperature strength of the grain boundaries and increase the creep strength of steel.

Residual nitrogen in mild steel can cause age brittleness. High-nitrogen steel has special advantages in terms of comprehensive properties such as strength, fracture toughness, wear resistance, magnetism, and corrosion resistance.

Ferrosilicon nitride is a ferroalloy material mainly composed of Si3N4, accompanied by free iron, non-silicon nitride, and a small number of other components.

Commercial ferrosilicon nitride for refractory is an off-white or brown powder, while steel-making ferrosilicon nitride is an off-white granular.

Granular ferrosilicon nitride is mainly used in silicon-oriented steel or other steels (Such as HRB400 rebar) that use nitrides to improve strength.
