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 because of the wear and tear of the guns. The military production department ordered Brillley to develop high-strength wear-resistant alloy steels to specifically address the wear and tear of the guns. Brellley and his assistants collected various types of steels produced at home and abroad, alloy steels of various properties, 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 this could not make a gun, so they recorded the experimental results and threw it at the corner. thing. One day a few months later, an assistant rushed to hold a piece of twilight steel and said to Brellley: "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!" Brellley 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.
