Historical origin of stainless steel

The invention and use of stainless steel dates back to the First World War. At that time, British guns on the battlefield were always shipped back to the rear because the bore was worn out. The military production department ordered Brearley to develop high-strength wear-resistant alloy steel, specifically to solve the problem of bore wear. Brearley and his assistants collected various types of steel produced at home and abroad, a variety of different properties of alloy steel, on a variety of different properties of machinery performance experiments, and then choose the more suitable steel to make guns. One day, they experimented with an alloy steel containing a lot of chromium, and after wearing resistance tests, they found that this alloy was not wear-resistant, indicating that it could not make guns, so they recorded the results of the experiment and threw it into the corner. One day a few months later, an assistant rushed to Brearley with a shiny piece of steel and said, "Sir, this is the alloy steel sent by Mr. Mullah that I found when I was cleaning the warehouse. Would you like to test it to see what special effect it has?" 'Good! Brearley said happily, looking at the shiny steel.
Experimental results show 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 mullahs in 1912, however, the mullahs did not know what purpose this stainless steel had.
Brearley thought to himself, "This non-abrasive but corrosion-resistant steel can't be made into guns. Can it be made into tableware?" He said to dry, and began to make stainless steel fruit knives, forks, spoons, fruit trays and folding knives.
Brearley invented stainless steel in 1916 obtained a British patent and began mass production, so far, the stainless steel accidentally found in the garbage has become popular around the world, Henry Brearley is also known as the "father of stainless steel".
