Stainless steel is a steel that is not easy to rust under normal conditions. It can withstand the corrosion of weak corrosive media such as air and water and chemical corrosive media such as acid, alkali and salt. Among them, the corrosion resistance of weak corrosive media is usually called stainless steel. Corrosion resistant to chemically resistant media is called stainless acid resistant steel. The properties of stainless steel depend on the alloying elements incorporated therein. Different alloying elements are generally selected depending on the application.
Stainless steel was invented during the First World War and was invented by a British metallurgist named Brillley. It was during the war, and the demand for guns was very large. The barrel of the gun used at that time was very rusty and very unreliable: Brellley received the request to develop a steel that would not easily rust. To make the barrel, in a test, Brillley incorporated chromium into the steelmaking material and refined a very bright steel: but the steel was very brittle. Not suitable for barrels, so Brillley threw the steel into the trash can.
after a while. Brillley inadvertently discovered that the steel in the trash can still be bright and rust-free. Brelley discovered through research that it is the chromium that is incorporated into the steel that makes it difficult to rust. Brellley introduced stainless steel to a tableware factory, which made stainless steel begin to enter people's lives.
