1 . (
Chem .)
The most common and most useful metallic element ,
being of almost universal occurrence ,
usually in the form of an oxide (
as hematite ,
magnetite ,
etc .),
or a hydrous oxide (
as limonite ,
turgite ,
etc .).
It is reduced on an enormous scale in three principal forms ;
viz ., {
cast iron },
steel ,
and {
wrought iron }.
Iron usually appears dark brown ,
from oxidation or impurity ,
but when pure ,
or on a fresh surface ,
is a gray or white metal .
It is easily oxidized (
rusted )
by moisture ,
and is attacked by many corrosive agents .
Symbol Fe (
Latin Ferrum ).
Atomic number 26 ,
atomic weight 55 .
847 .
Specific gravity ,
pure iron ,
7 .
86 ;
cast iron ,
7 .
1 .
In magnetic properties ,
it is superior to all other substances .
[
1913 Webster ]
Note :
The value of iron is largely due to the facility with which it can be worked .
Thus ,
when heated it is malleable and ductile ,
and can be easily welded and forged at a high temperature .
As cast iron ,
it is easily fusible ;
as steel ,
is very tough ,
and (
when tempered )
very hard and elastic .
Chemically ,
iron is grouped with cobalt and nickel .
Steel is a variety of iron containing more carbon than wrought iron ,
but less that cast iron .
It is made either from wrought iron ,
by roasting in a packing of carbon (
cementation )
or from cast iron ,
by burning off the impurities in a Bessemer converter (
then called Bessemer steel ),
or directly from the iron ore (
as in the Siemens rotatory and generating furnace ).
