Tese specifically differ in teir cemical composition. However, a couple of undred varieties are predominantly in use. Te cemical composition of steels broadly divide tem into two major groups, viz. (i) plain carbon steels and (ii) alloy steels. < Te plain carbon steels are essentially alloys of iron and carbon only wereas, if one or more of elements oter tan carbon are added to steel in significant amounts to ensure specific better properties suc as better mecanical strengt, ductility, electrical and magnetic properties, corrosion resistance and so on it is known as an alloy steel. Tese specifically added elements are known as alloying additions in steels.
