Origin of stainless steel

Date:May 13, 2019

The invention and use of stainless steel date back to the first world war.

During the first world war, British guns on the battlefield were always shipped back to the rear because the bore was worn and could not be used. Harry Brearley, a British scientist who worked on high-strength wear-resistant alloy steel, was ordered by the military production department to specialize in solving the problem of gun bore wear. In 1913, entrusted by the British government military department Arsenal, brealli and his assistants collected all kinds of types of steel produced at home and abroad, all kinds of alloy steel with different properties, carried out performance tests on various kinds of mechanical properties, and then selected more suitable steel to make guns. Henry brealli works at a metallurgical laboratory in sherfield, England. He mixed different elements into the steel to mold the barrel and then tested its hardness. He knew that steel was an alloy of carbon and iron, and that many other elements could be added to iron to strengthen or weaken its properties, but no one knew why. So he began to experiment, melting iron and adding various ingredients to see what would happen, but nothing worked. Later a chance, just let stainless steel face in the world. By 1916, stainless steel was patented in the United Kingdom and mass-produced. As a result, stainless steel discovered by accident in a rubbish dump was so popular around the world that Henry braille was known as the "father of stainless steel".
