The Making of Iron & Steel
4 2 Materials Used to make Steel 2.1 Iron Ore Composition Iron very rarely occurs in the earth''s surface as a metal. It is widely distributed, coined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth''s crust.

Infographic: the Iron and Steel Manufacturing Process
Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from 150kg in 2001 to 225 kg in 2013.

2I Secondary Refining
Thus, secondary refining has recently become the standard process for producing high-grade steels. The most important functions of secondary refining are final desulfurization, degassing of oxygen, nitrogen, hydrogen, etc., removal of inclusions, and final decarburization for ultra-low carbon steel.

The 6 Steps in the Manufacturing Process of a Stainless …
Even though there are billions of users of stainless steel items around the world, there are very few people (relatively) who know what goes into making a stainless steel product from scratch. The manufacturing process of a stainless steel product is indeed fascinating and it gives you an insight into how far our ability to craft materials has evolved since the early days of the Industrial
