The Steel Manufacturing Process

10 04 2020  The modern day steel production process began in 1856 under a process known as the Bessemer process It s largely considered to be the first process used to mass produce steel According to historians two different inventors one in the UK and one in Pittsburgh both simultaneously developed a steel production process that involved removing iron s impurities through the use of an air blast.
