Demystifying FeE390KG Steel Grade: The Science Behind its Resilience and Longevity

FeE390KG is a steel grade that is widely used due to its exceptional resilience and longevity. In this article, we aim to demystify this steel grade by delving into its mechanical properties and chemical composition.

Mechanical Properties:
FeE390KG exhibits excellent strength and toughness, making it suitable for various applications requiring high structural integrity. Its tensile strength is typically within the range of 390-500 megapascals (MPa), providing the steel with the ability to withstand heavy loads and impacts without suffering deformation or failure. The yield strength of FeE390KG is around 390 MPa, indicating its ability to resist permanent deformation under stress.

Another important mechanical property of FeE390KG is its elongation, which reflects the steel’s ability to deform plastically before fracturing. FeE390KG typically has an elongation of around 25%, signifying its excellent ductility and formability. This characteristic enables the steel to be easily shaped and fabricated without compromising its structural integrity.

Furthermore, FeE390KG exhibits good hardness, with a typical range of 190-230 Brinell hardness. This hardness allows the steel to resist wear, abrasion, and penetration, making it suitable for applications in harsh environments or those involving contact with abrasive materials.

Chemical Composition:
The chemical composition of FeE390KG steel grade plays a crucial role in determining its mechanical properties and overall performance. The main elements in FeE390KG include carbon (C), manganese (Mn), silicon (Si), phosphorus (P), and sulfur (S).

Carbon is a key element in steel, influencing its strength and hardness. FeE390KG typically has a carbon content of around 0.20-0.25%, which contributes to its high tensile strength and hardness.

Manganese is added to improve the steel’s strength and toughness. FeE390KG usually contains manganese within the range of 1.50-1.80%. This element enhances the steel’s hardenability, making it suitable for applications that require increased resistance to wear and impact.

Silicon is added to FeE390KG in small amounts (typically around 0.15-0.35%) to enhance its deoxidation properties and improve the steel’s strength and ductility.

Phosphorus and sulfur are impurity elements that are often controlled within low levels in FeE390KG. Phosphorus acts as a strengthener but can also reduce the steel’s toughness if present in excessive amounts. Sulfur, on the other hand, can negatively affect the steel’s ductility and toughness. Therefore, FeE390KG steel grade usually has low levels of phosphorus and sulfur, typically below 0.040% and 0.050%, respectively.

In conclusion, FeE390KG steel grade is renowned for its resilience and longevity. Its impressive mechanical properties, including high strength, toughness, elongation, and hardness, make it suitable for various demanding applications. The chemical composition, characterized by controlled levels of carbon, manganese, silicon, phosphorus, and sulfur, contributes to the steel’s exceptional performance.
