The second most abundant chemical element on the earth’s surface.
It is used in the steel refining processas a deoxidizer and is an element that in the form of silica appears in great part of the refractories used in the steel industry.
As an alloying element in carbon steels increases the yield strength, being one of the main alloying elements in spring steels or of high yield strength. It is also used to make magnetic plate.
In structural steels, depending on the percentage of silicon, the suitability for hot dip galvanizing is determined.
