Do you know who invented stainless steel more than 100 years ago?
Harry Brearley, born in 1871. The story goes that in 1915, while searching for a metal that could better resist erosion caused by high temperatures, the metallurgist began to consider adding chromium to steel, thus raising its melting point compared to standard carbon steels. It was then that he discovered that the new chromium steels were very resistant to chemical attack. It was then his successor, Dr WH Hatfield, who in 1924 achieved a stainless steel: the so-called 18/8.
