1912 Steel goes stainless The invention of stainless steel, which was officially 100 years old in May 2012, is normally attributed to one Harry Brearley from Sheffield Chrysler building detail
By all indications, steel was first discovered and produced in eastern Africa sometime around 1400 B.C. The technology spread slowly; it wasnât until the first century A.D. that the rest of the continent was also producing steel. Africans were first elsewhere, too. Even the Iron Age had come early to the continent, probably in the sixth century B.C. Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1%, depending on the grade.
