The invention and use of stainless steel dates back to the First World War. British scientist Henry Borelli commissioned by the British government military arsenal to study the improvement of weapons work. At that time, the soldiers with the rifle guns easy to wear, Borelli would like to invent a kind of wearable alloy steel.

The stainless steel invented by Bregra was made British patent 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." In the First World War, the British guns on the battlefield, always because of gun wear can not be used and shipped back to the rear. The military production department ordered Borelli to develop high-strength wear-resistant alloy steel, specializing in solving the problem of gun wear. Blairley and its assistants collected various types of steel, various types of alloy steels produced at home and abroad, carried out performance tests on various mechanical properties, and then chose a more suitable steel for guns. One day, they experimented with a large amount of chrome-containing domestic alloy steel, the wear-resistant test, to identify the alloy is not wearable, indicating that this can not produce guns, so they recorded the experimental results, to the corner thing. A few months later, an assistant took a piece of steel with a piece of light, and said, "Sir, this is the alloy steel that I found when I was cleaning up the warehouse. Whether it is experimental, to see what the special role in the end! "" Good! "Borelli looked at the bright steel, happy to say.
