Ferro silicon magnesium
Ferro silicon magnesium has transform sheet grate to srical shape to produce of ductile iron and increase hardness compare to gray iron.
It is also caused to increase impact of resistance, toughness and hardness alongside of carbide decreasing in foundry thin sections, machining improvement, increase ferrite and decreasing steel brittleness and heat treatment charges.
This alloy use in steel cleaning and purification, additive in stainless steel, silicon steel and carbon steel too.
