The Steel Story
13th century BC Invention of steel - iron and charcoal come together Early blacksmiths discovered that iron became harder and stronger when left in charcoal furnaces.
3rd century BC Wootz steel: Born in ancient India As early as the third century BC,  the craftsmen of southern India used crucibles to smelt wrought iron with charcoal to produce ‘wootz’ steel – a material that is still admired today.

Roman Era With war comes progress Imperial armies, including those of China, Greece, Persia and Rome, were eager for strong, durable weapons and armour. The Romans learned how to temper work-hardened steel to reduce its brittleness.

During this time, expensive steel was produced in limited quantities by artisans, and expensive was also used in applications other than armour and weaponry. Sweden led the way during the 18th century - new techniques began to emerge, which improved quality and consistency. VIDEO

1914-18 War again World War I weaponry consisted of various types of steel weapons standardised and improved over the preceding period together with some newly developed types using innovative technology and a number of improvised weapons used in trench warfare. Military technology led to important innovations in weaponry, grenades, poison gas, and artillery, along with the submarine, warplane and the tank. IMAGE GALLERY
1939-45 More war The 20th century’s two world wars had huge consequences for steelmaking. Like other heavy industries, steelmaking was nationalised in many countries due to demands for military equipment. Steel was required for the railways and ships that carried troops and supplies. Steel plates proved vital in the development of shipping and other forms of transport, as well as for obvious military uses.

1950s-60s Steel for comfort and lifestyle In the 1950s and 60s, significant developments were made in steel processes, which allowed production to move away from military and shipping to cars and home appliances, which brought a huge growth in the range of steel home appliances that were made available to consumers.

The future Steel is 100% recyclable with no downgrading in quality, which makes steel the most recycled material in the world. But steelmaking is not isolated - it is governed by many laws, rules, regulations and restrictions. Therefore, as we look to the future, governments and society must make informed decisions on where and how to sensibly add extra rules and restrictions. Successful steelmaking must operate within these frame works and continue to explore new sustainable ways forward into the future. How its made - Metal recycling How its made - Metal recycling
