Steel is obtained by properly mixing carbon into iron. In the iron and steel industry, those with a carbon content of less than 2.11% are called steel, and those with a carbon content greater than 2.11% are called iron.
Stainless steel is also called alloy steel. Cobalt, Chromium, nickel, tungsten, titanium and other metals.
"Iron-carbon alloy" with a carbon content of less than 2%, this steel is called "carbon steel". Carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel according to the carbon content.
Adding other synthetic elements into the steel is called "alloy steel". The purpose of smelting alloy steel is to meet the needs of production and life.
Stainless steel is a kind of alloy steel, adding more metal alloy elements such as Ci and Ni, and there are many types.
Common stainless steel is divided into "ferritic stainless steel" and "austenitic stainless steel"
Ferritic stainless steel has a body-centered lattice and is magnetic. For example: 1Ci13, 2Ci13. Often used to make tableware and decorative pieces.
Austenitic stainless steel is a face-centered lattice and non-magnetic. For example: 1Ci18Ne9T, used in chemical, pharmaceutical and food industries. If someone says that it is not comprehensive to use magnets to distinguish whether it is stainless steel or not.
