Steel is an alloy of iron, carbon, and small amounts of other elements； It is a general term for iron-carbon alloys with a mass percentage of carbon ranging from 0.02% to 2.06%.
It is a general term for iron-carbon alloys with a mass percentage carbon content ranging from 0.02% to 2.11%.
Steel is an iron-carbon alloy with a carbon content ranging from 0.0218% to 2.11%. We usually refer to it together with iron as steel; to ensure its toughness and ductility, the carbon content generally does not exceed 1.7%. The main elements of steel, in addition to iron and carbon, include silicon, manganese, sulfur, phosphorus, etc. Other components are used to give the steel different properties.
