The historical origin of stainless steel:

The invention and use of stainless steel dates back to the first World War. Henry Brearley, an English scientist, was commissioned by the British Government's Armory to work on the improvement of weapons. At the time, soldiers' rifles bore easily, and Brearley wanted to invent alloy steel that would not wear.

Brearley invented stainless steel in 1916 obtained the British patent and began to mass production, so far, the stainless steel accidentally found in the garbage became popular all over the world, Henry Brearley is also known as the "father of stainless steel". During the First World War, British guns on the battlefield were always sent back to the rear because the chamber was worn and unusable. The military production department ordered Brearley to develop high-strength wear-resisting alloy steel, specializing in solving the problem of the bore wear. Brearley and his assistant collected various types of steel produced at home and abroad, a variety of different properties of alloy steel, in a variety of mechanical properties of performance experiments, and then select the more suitable steel into guns. One day, they tested a kind of domestic alloy steel containing a lot of chromium. After the wear-resisting test, it was found that this alloy was not wear-resisting, indicating that it could not be used to make guns. So they recorded the results of the experiment and threw them into a corner. One day, a few months later, an assistant rushed to Brearley with a shiny piece of steel. "Sir," he said, "I found the alloy from Mr. Mullah when I was cleaning out the warehouse. Would you like to test it to see what special use it has!" "Good!" Brearley said happily, looking at the shining steel.

Experimental results show that it is not afraid of acid, alkali, salt stainless steel. The stainless steel was invented by a German mullah in 1912, but the mullah had no idea what it was for.

Brearley wondered: "Can this kind of steel, which is not wear-resistant but corrosion-resistant, be used for tableware, not for guns?" He said dry dry, began to make stainless steel fruit knife, fork, spoon, fruit plate and folding knife.
