Stainless steel is different from the main symbol of carbon steel is in addition to carbon content, no other people to join other alloying elements. Carbon steel generally do not have any corrosion resistance, hardness than pure iron, of course, carbon is also controlled to a certain extent.
Many types of stainless steel, refers to the amount of steel is greater than or equal to 13%, in the atmosphere of stainless steel alloy. There are austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and so on. Stainless steel generally does not have magnetic, but not absolute, austenite is not magnetic, but ferritic has, but also relatively weak. Different stainless steel resistance to corrosion is different, different corrosive to different media.
Regarding the difference carbon steel and stainless steel, generally believed that the first is in terms of corrosion resistance. However, stainless steel in practical applications, with its excellent performance, with other steel can not replace the role, such as some high temperature stainless steel, such as stainless steel excellent surface properties for a large number of decorative materials, as well as stainless steel excellent machinery Performance in the use of various types of manufacturing.
Ordinary steel is carbon steel, that is, iron-carbon alloy. According to the level of carbon content, pided into low carbon steel (wrought iron), medium carbon steel and cast iron. General carbon content of less than 0.2% called low carbon steel, commonly known as wrought iron or pure iron; content of 0.2-1.7% called steel; content of more than 1.7% called pig iron.
