State of iron at room temperature
WebAt pressures above approximately 10-13 GPa and temperatures up to around 700 K, α-iron changes into a hexagonal close-packed (hcp) structure, which is also known as ε-iron or hexaferrum; the higher-temperature γ-phase also changes into ε-iron, but generally requires far higher pressures as temperature increases. WebAt room temperature, it exists in the ferrite state. Steel is an iron carbon alloy with a carbon content ranging from 0.008 to 2.14 percent. Steel grades within this range are known as low carbon steel (or mild steel), medium carbon steel, and high carbon steel. When the carbon content exceeds 2.14 percent, we reach the cast iron stage. Cast ...
