Unlocking the Potential of FeE390KG Steel Grade: Enhanced Performance in Extreme Environments

The specification of FeE390KG steel grade for enhanced performance in extreme environments includes the following mechanical properties:

1. Tensile Strength: The FeE390KG steel grade has a minimum tensile strength of 390 Megapascal (MPa). This measures the maximum amount of stress the steel can withstand before breaking or fracturing.

2. Yield Strength: The FeE390KG steel grade has a minimum yield strength of 390 MPa. This is the stress at which the steel begins to deform permanently, indicating its ability to resist deformation under load.

3. Elongation: FeE390KG steel grade has a minimum elongation of 22%. Elongation measures the amount of plastic deformation a material undergoes before fracturing. A higher elongation percentage indicates better ductility and the ability to absorb energy before failure.

4. Impact Strength: FeE390KG steel grade has a minimum impact strength of 39 Joules (J). This measures the energy absorbed by the steel when subjected to an impact load. A higher impact strength indicates better resistance to sudden loads or impacts without fracturing.

The chemical composition of FeE390KG steel grade includes the following elements:

1. Carbon (C): FeE390KG steel grade contains a maximum of 0.20% carbon. Carbon improves hardness and strength but can reduce ductility if present in high quantities.

2. Silicon (Si): FeE390KG steel grade contains a maximum of 0.50% silicon. Silicon improves the strength and durability of the steel and also helps in deoxidization during the steelmaking process.

3. Manganese (Mn): FeE390KG steel grade contains a maximum of 1.50% manganese. Manganese improves the hardenability and strength of the steel, and it also helps in deoxidizing and desulfurizing the steel during manufacturing.

4. Phosphorus (P): FeE390KG steel grade contains a maximum of 0.045% phosphorus. Phosphorus can adversely affect the steel’s ductility, so it is kept to a minimum to ensure good formability.

5. Sulfur (S): FeE390KG steel grade contains a maximum of 0.045% sulfur. Excess sulfur can reduce the toughness and weldability of the steel, so it is controlled within specified limits.

6. Other elements: FeE390KG steel grade may contain trace amounts of other elements such as chromium (Cr), nickel (Ni), copper (Cu), and molybdenum (Mo) to enhance specific properties or improve machinability.

These mechanical properties and chemical composition specifications ensure that FeE390KG steel grade exhibits enhanced performance in extreme environments, providing the necessary strength, durability, and resistance to environmental factors such as temperature, corrosion, and impact.
