Stainless steel is the abbreviation of stainless and acid-resistant steel, and steel or stainless steel resistant to weak corrosive media such as air, steam and water is called stainless steel. Steel resistant to chemical corrosive media (acid, alkali, salt and other chemical corrosion) is called acid-resistant steel.
Their corrosion resistance is different due to their different chemical compositions. Ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid-resistant steel is generally stainless. The word "stainless steel" refers not only to one kind of stainless steel, but to 100 kinds of industrial stainless steel, and each developed stainless steel has good performance in its specific application field. The key to success is to find out the purpose first, and then determine the correct steel grade.
Historical origin
The invention and use of stainless steel can be traced back to the First World War. Henry buhrer, a British scientist, was commissioned by the British military arsenal 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".
