How are iron and carbon used to make steel?How are iron and carbon used to make steel?In its pure form, iron is soft and generally not useful as an engineering material; the principal method of strengthening it and converting it into steel is by adding small amounts of carbon. In solid steel, carbon is generally found in two forms.

Sulfur, in particular, promotes internal segregation in the steel matrix. Both act to reduce the ductility of the material.

They are commonly used for attaching screed bar holder clamps in flatwork finishing, securing landscape timbers and surveying stakes.Creating Steel HowStuffWorksThe open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag.Deoxidation of Steel IspatGuruSep 03, 2014Deoxidation is the last stage in steelmaking. During making of steel, the steel bath at the time of tapping contains 400 to 800 ppm activity of oxygen. Deoxidation is carried out during tapping by adding into the teeming ladle appropriate amounts of ferro alloys or other special deoxidizers.

Steel plate can be both improved and formed by controlled explosions. In this process a die is submerged in water and a steel plate lowered over it. A charge is set off in the water above the metal. The blast forces the plate down until it assumes the shape of the die. Steel plates of light gauge can be shaped in this way.
