Historical Origin Of Stainless Steel

The invention and use of stainless steel can be traced back to World War I. At that time, British firearms on the battlefield were always transported back to the rear due to worn and unusable rifles. The military production department ordered Brelly to develop high-strength wear-resistant alloy steel, specifically to study and solve the problem of gun bore wear. Brelly and his assistants collected various types of steel and alloy steel produced domestically and internationally, conducted performance experiments on various mechanical properties, and then selected more suitable steel to make firearms. One day, they experimented with an alloy steel containing a large amount of chromium. After wear resistance experiments, it was found that this alloy was not wear-resistant, indicating that it could not manufacture firearms. Therefore, they recorded the experimental results and threw it at the corner of the wall. One day a few months later, an assistant rushed to Brelly with a shiny piece of steel and said, "Sir, this is the alloy steel that Mr. Mullah sent me while cleaning the warehouse. Would you like to experiment with it and see what special function it has?" "Okay!" Brelly looked at the shiny steel and said happily.
The experimental results prove that it is a stainless steel that is not afraid of acids, alkalis, or salts. This type of stainless steel was invented by the German Mullah in 1912, but the Mullah was unaware of its purpose.
Brelli thought to himself, "This kind of wear-resistant but corrosion-resistant steel cannot be used to make firearms. Can it be used to make tableware?" He said and went ahead, making stainless steel fruit knives, forks, spoons, fruit trays, and folding knives.
The stainless steel invented by Bradley was patented in the UK in 1916 and began mass production. From then on, stainless steel discovered accidentally from garbage piles became popular worldwide, and Henry Bradley was also known as the "father of stainless steel".
