The invention and use of stainless steel dates back to the First World War. British scientist Henry Brelley was commissioned by the British Government Military Arsenal to study the improvement of weapons. At that time, the rifle barrel used by soldiers was very easy to wear, and Brelley wanted to invent an alloy steel that was not easy to wear.
The stainless steel invented by Brairley obtained the British patent right in 1916 and began mass production. So far, the stainless steel accidentally discovered from the garbage dump was swept the world, and Henry Brairley was also known as "the father of stainless steel". During the First World War, British guns on the battlefield were always transported to the rear due to worn out gun barrels. The military production department ordered the development of Brairley, a high-strength wear-resistant alloy steel, which specializes in solving the problem of gun barrel wear. Brairley and his assistants collected various types of steels produced at home and abroad, alloy steels with different properties, performed performance experiments on various different types of machinery, and then selected more suitable steels to make guns. One day, they experimented with a domestic alloy steel containing a large amount of chromium. After abrasion tests, they found that the alloy was not abrasion-resistant, indicating that it was not possible to manufacture guns. So they recorded the results of the experiments and threw them into the corner thing. One day a few months later, an assistant rushed to Brelley with a piece of shiny steel and said, "Sir, this is the alloy steel sent by Mr. Mullah when I found the warehouse. You Let's experiment and see what special effect it has! "" Okay! "Brelley looked at the bright steel and said happily.
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 the German Mullah in 1912. However, Mullah did not know what the stainless steel was for.
Brairley thought, "This steel that is not wear-resistant but corrosion-resistant cannot be used for making guns. Can it be used as tableware?" And folding knives.
