The invention and use of stainless steel dates back to the First World War. British scientist Henry Blairley was commissioned by the British Army Department's Arsenal to study the improvement of weapons. At that time, the rifle bore used by soldiers was very easy to wear and tear, and Bradley wanted to invent an alloy steel that was not easy to wear and tear.
The stainless steel invented by Bradley was patented in Britain in 1916 and began mass production. Since then, stainless steel discovered by chance from garbage dumps has become popular all over the world. Henry Bradley is also known as the "father of stainless steel". During World War I, British guns on the battlefield were always brought back to the rear because their bores were worn out and unusable. The military production department ordered the development of high strength wear-resistant alloy steel Bradley, which specializes in solving the wear problem of gun bore. Bradley and his assistants collected various types of steel and alloy steels produced at home and abroad, and carried out performance experiments on various mechanical properties. Then, they selected suitable steels to make guns. One day, they experimented with a domestic alloy steel containing a large amount of chromium. After wear-resistant experiments, they found that the alloy was not wear-resistant, indicating that it could not make guns. So they recorded the experimental results and threw things into the corner. A few months later, an assistant rushed to Bradley with a shiny piece of steel and said, "Sir, this is the alloy steel that Mr. Mullah sent me when I was cleaning the warehouse. Would you like to experiment and see if it has any special function?" "Good!" Bradley looked at the shiny steel and said happily.
The experimental results show that it is a stainless steel fearless of acid, alkali and salt. The stainless steel was invented by the German Mullah in 1912. However, the Mullah did not know what the purpose of the stainless steel was.
Bradley thought to himself, "This kind of steel, which is not wearable but corrosion-resistant, can't make guns. Can it be used as tableware?" He said that he could do it, and made stainless steel fruit knives, forks, spoons, fruit plates and folding knives.
