The stainless steel invented by Blairley obtained a British patent in 1916 and began mass production. Since then, the stainless steel accidentally found in the garbage dump has become popular all over the world, and Henry Blairley is also known as the "father of stainless steel." During the First World War, British guns on the battlefield were always transported back to the rear because their barrels were worn out. The military production department ordered Blairley, who developed high-strength wear-resistant alloy steel, to specialize in solving the problem of gun bore wear. Blairley and his assistants collected various types of steels and alloy steels of different properties produced at home and abroad, conducted performance experiments on machines of various properties, and then selected more suitable steels to make guns. One day, they experimented with a domestic alloy steel that contains a lot of chromium. After wear-resistant experiments, they found that this alloy was not wear-resistant, indicating that it could not make guns a. So they recorded the results of the experiment and threw them into the corner It's up. One day a few months later, an assistant rushed to Blairley with a piece of shiny steel and said, "Sir, this is the alloy steel from Mr. Mullah that I found when I was cleaning the warehouse. You Do you experiment to see what special effect it has!" "Okay!" Breerley said happily, looking at the dazzling steel.　　

　　 The experimental results prove that it is a piece of stainless steel that is not afraid of acid, alkali, and salt. This stainless steel was invented by a German mullah in 1912, however, the mullah did not know what purpose this stainless steel had.

　　Blairley thought to himself: "This kind of non-wearing but corrosion-resistant steel can't be used to make guns. Can it be used as tableware?" He just said it and made stainless steel fruit knives, forks, spoons, and fruit plates. And folding knives, etc.
