From Strength to Sustainability: StE380 Steel Grade in Sustainable Construction

The StE380 steel grade is commonly used in sustainable construction due to its high strength and durability. It offers a balance between strength, toughness, and weldability, making it suitable for various structural applications.

The mechanical properties of StE380 steel are as follows:

– Tensile strength: It has a minimum tensile strength of 380 MPa.
– Yield strength: It has a minimum yield strength of 380 MPa.
– Elongation: The minimum elongation is 20% (Longitudinal test piece).

These mechanical properties ensure that the StE380 steel grade provides sufficient strength to withstand applied loads and structural stresses, making it suitable for sustainable construction projects.

The chemical composition of StE380 steel typically includes the following elements:

– Carbon (C): It has a maximum carbon content of 0.20%, contributing to the steel’s strength and hardness.
– Manganese (Mn): It has a maximum manganese content of 1.50%, which enhances the steel’s strength and improves its weldability.
– Phosphorus (P): It has a maximum phosphorus content of 0.035%, which helps improve the steel’s strength and corrosion resistance.
– Sulfur (S): It has a maximum sulfur content of 0.035% to ensure good machinability and smooth surface finish.
– Silicon (Si): It has a maximum silicon content of 0.50%, contributing to the steel’s strength and malleability.
– Nitrogen (N): It has a maximum nitrogen content of 0.012%, which improves the steel’s strength and toughness.

These chemical components play a crucial role in determining the mechanical properties and overall performance of StE380 steel, making it a suitable choice for sustainable construction projects.
