Harry buhrer, a famous metallurgist who graduated from the University of Sheffield in England, invented stainless steel in the early 20th century. The invention and use of stainless steel can be traced back to the First World War. British scientist BuHenry buhrer was commissioned by the British military factory to study the improvement of weapons. At that time, the rifle bore used by soldiers was very easy to wear, and buhrer wanted to invent an alloy steel that was not easy to wear. The stainless steel invented by buhrer Leigh was patented in Britain in 19 16, and mass production began. Since then, stainless steel accidentally found in garbage has swept the world, and Henry buhrer Leigh is also known as the "father of stainless steel".
