Did you know that stainless steel was invented because of war?

It is said that in the first World War in 1914, Britain, France and Germany launched a fierce battle, it is not so advanced weapons, the quality of British soldiers rifles is not good, often used after particularly easy to wear, so at that time want to create a new gun, but the material is particularly expensive, the British government is very headache, decided to re-develop a new bore resistant to wear.

This task was given to Brearley, who was a famous metal expert in Britain at that time, when he received the task, he began to study, a long time passed, but Brearley's development work did not make substantial progress, in the corner of the laboratory, all kinds of discarded steel piled up into a hill. Brearley regained his confidence. He decided to clean up the lab for new experiments.

Suddenly, a researcher cried out, "Why is this alloy steel silver shiny, shiny, there is no rust?" "It does not rust, indicating that it is not easily corroded by air, so what is it easily corroded by?" It turned out to be chrome, which Brearley eliminated because it wasn't hard enough to wear out easily. So if you can't do guns, what can you do? It is also the function of waste utilization, and finally made into knives and forks, which is the source of stainless steel.

Brearley's invention of stainless steel in 1916 obtained a British patent and began mass production, so far, from the trash accidentally found stainless steel has become popular around the world, Brearley is also known as the "father of stainless steel."
