What is the carbon content of pig iron, ordinary steel and stainless steel?
Iron carbon content is generally 2%~4%; low carbon steel: steel has high carbon content of 0.6~2.0, 0.3~0.6, < 0.3; 300 stainless steel carbon content is lower than 0.8%, the other high alloy steel carbon content is less than 0.3%, 400 carbon steel slightly higher martensite.
The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steel is lower, the maximum is not more than 1.2%, and the Wc (carbon content) of some steel is even lower than 0.03% (such as 00Cr12).
Definition of steel: iron carbon alloy with carbon content less than 2.11%. The carbon content of industrial cast iron (pig iron) is between 2%~4%
