Briefly describe the content of carbon in steel and its effect on the properties of steel

Generally, the C<2.11% in the Fe-C melt is called steel, and the C<0.02 is called industrial pure iron, so the steel C is between 0.02% and 2.11%.

The steel containing C generally has the following effects on its properties:

C hardness increases strength

toughness and plasticity decrease

weldability is poor

and corrosion is also deteriorated.
