Metal Profile Iron Properties and Characteristics

Oct 29, 2018Iron was likely originally discovered and extracted as a result of wood burning on top of iron containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present day Iraq) between 2700 and 3000 BC.

Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle.
