Medium carbon steel, abbreviated as MCS, is a type of carbon steel that strikes a balance between the properties of low-carbon and high-carbon steels. It typically contains a carbon content ranging from 0.30% to 0.60%, and often includes a manganese content between 0.60% and 1.65%. This composition provides a good combination of strength, ductility, and toughness, making it a versatile material. Medium carbon steel can also be heat-treated through processes like quenching and tempering to further enhance its hardness and mechanical properties. Due to its balanced characteristics, it is widely used in various applications, including automotive parts (such as shafts, axles, and crankshafts), machinery components, gears, and structural steel. While it offers good strength and wear resistance, it is generally less corrosion-resistant than stainless steel and can be more brittle than low-carbon steel if not properly heat-treated.
Mediun Carbon Steel is Primarily Composed of the Following Elements
Carbon (C) - 0.30% to 0.60%
Manganese (Mn) - 0.60% to 1.65%
Iron (Fe) - Balance (major component)
Silicon (Si) - ≤ 0.60%
Sulfur (S) - ≤ 0.05% (impurity)
Phosphorus (P) - ≤ 0.04% (impurity)
Optional minor alloying elements (depending on grade):
Chromium (Cr), Nickel (Ni), or Molybdenum (Mo) - Added in small amounts for specific properties such as strength or hardness.
