Ferro silico zirconium

Adding 0.005 to 0.01% by weight of zirconium as a micro alloy element on the mechanical properties of plain carbon steel casting increases the hardness and impact toughness of plain carbon steel. Also, as a result of heat treatment, the effect of adding zirconium on hardness is more noticeable. On the other hand, the changes in the impact toughness of sub-conium microalloy steel are not noticeable in the temperature range of 40 to 20 degrees Celsius.

Application: production of microalloy steel to improve mechanical properties
