Harry Brearley, a famous metallurgical scientist at the University of Sheffield in the UK, invented stainless steel in the early 20th century. The invention and use of stainless steel dates back to the First World War. British scientist Bessley Borelli was commissioned by the British Military Army Arsenal to study the improvement of weapons. At that time, the soldiers used to rifle guns easy to wear, Borelli would like to invent a kind of wearable alloy steel. The stainless steel invented by Borelli made British patents in 1916 and began mass production. At this point, stainless steel, which was accidentally discovered from the rubbish, was swept the globe, and Henry Brayley was also known as the "father of stainless steel."
