About Pure Iron:
The tensile strength of a single crystal of
pure iron is about 4000 lb/in2. If as
little as 0.2% carbon is added, the tensile
strength approaches 60,000 lb/in2.
The tensile strength of a plain carbon steel
with 0.8% carbon is over 110,000 lb/in2.
Iron is soft, ductile, magnetic. Its relative
resistance to corrosion increases with relative
purity. Iron is easily contaminated. Iron
electrical resistivity at
20°C is 9.7 microhms per cm3 at
temperature coefficient at 0°C is 0.00651 ohm
per °C. In the form of electrolytic iron
containing large amounts of absorbed hydrogen ,
iron is hard, brittle, and readily powdered.
