Exploring the Complexity of Steel
Steel is primarily composed of iron and carbon, but its definition lacks precision due to the multitude of grades and types available. The basic distinction between steel and cast iron is that steel contains less than 2.1% carbon, while cast iron contains more, resulting in different properties. The phases of steel are categorized by how carbon is distributed at varying temperatures, leading to various forms such as martensite, bainite, and pearlite. Understanding these phases is crucial as the transformation of steel through cooling or heating significantly affects its strength and toughness.
