Difference
between steel & iron steel
In contrast to steel, iron steel has more content of iron than carbon. It
contains chemically pure iron and also is referred to as ferrous alloys. If
more carbon is added to iron it becomes carbon steel and adding higher
carbon to steel it becomes cast iron. So, basically iron means chemically
pure iron. Since iron contains minimal amount of carbon, it becomes softer
upon heating and could easily shaped using a hammer. Unlike steel, iron
cannot be hardened by heat treatment.
Usages of steel iron pipes and tubes:
The strength of the Iron steel makes it a perfect material for
manufacturing pipes. Iron steel pipes possess ultimate tensile strength,
yield strength and hardness, at the same time these are corrosion resistant.
Iron steel is available in a variety of finishes including galvanized, paint
over galvanized (powder coat or liquid), dulled and darkened galvanizing.
Usually, iron steel pipes and tubing are lined with cement mortar. The aim
of this standard is to protect the internal surface of cast iron steel pipes
and fittings used in pipelines. Iron steel tubes and pipes are utilized in
the transportation and distribution of water for domestic and industrial
use.
