Construction cost & co.

Steels are alloys of iron and other elements, primarily carbon, widely used in construction and other applications because of their hightensile strengths and low costs. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement ofdislocations that otherwise occur in the crystal lattices of iron atoms.

 

The carbon in typical steel alloys may contribute up to 2.1% of its weight.
