Harry Brearley, a famous metallurgical scientist who graduated from the University of Sheffield in the United Kingdom, invented stainless steel in the early 20th century. The invention and use of stainless steel dates back to the First World War. British scientist Buxley Brellley was commissioned by the British government military arsenal to study the improvement of weapons. At that time, the rifle guns used by the soldiers were extremely wearable, and Brillley wanted to invent an alloy steel that was not easy to wear. The stainless steel invented by Brillley acquired the British patent in 1916 and began mass production. Since then, the stainless steel accidentally discovered from the garbage dump has swept the world, and Henry Brellley is also known as the "father of stainless steel." During the First World War, the British guns on the battlefield were always transported back to the rear due to the wear and tear of the guns. The military production department ordered the development of Briali, a high-strength wear-resistant alloy steel, to specifically address the wear and tear of the gun. Briali and his assistants collected various types of steels produced at home and abroad, alloy steels of various natures, and carried out performance tests on various machines of different natures, and then selected the more suitable steel to make the guns. One day, they experimented with a domestic alloy steel containing a large amount of chromium. After the abrasion resistance test, it was found that the alloy was not wear-resistant, indicating that it could not make a gun. So, they recorded the experimental results and threw them at the corner. Something. One day a few months later, an assistant rushed with a bright steel to say to Briali: "Sir, this is the alloy steel that Mr. Mullah sent when I was cleaning the warehouse. You Do you experiment and see what special effects it has!" "Good!" Briali looked at the bright steel, happy to say. The experimental results prove that it is a stainless steel that is not afraid of acid, alkali and salt. This stainless steel was invented by the German Mullah in 1912. However, Mullah did not know what the stainless steel used. Briali's mind calculated: "This kind of steel that is not wear-resistant but corrosion-resistant, can't make guns, can you make tableware?" He said that he did it, and made stainless steel fruit knives, forks, spoons, fruit bowls and folding knives.
