Description
What Is EH500?
EH500 steel is an ultra-high-strength structural steel designed for shipbuilding and offshore engineering. Its composition includes carbon, silicon, manganese, phosphorus, and sulfur, carefully balanced to ensure excellent strength, weldability, and toughness. “E” stands for toughness level at -40℃, “H” indicates its high strength, while “500” refers to its minimum yield strength of 500 MPa.
This steel offers exceptional impact resistance, remaining tough even in low temperatures down to -40°C. It is also highly weldable and corrosion-resistant, making it suitable for marine environments. With easy processability, EH500 is widely used in shipbuilding, offshore platforms, bridges, construction, and heavy machinery, ensuring stability and durability across industries.
Characteristics of EH500
- Strong and durable, capable of handling heavy loads.
- Resistant to corrosion and extreme environments.
- Offers a high strength-to-weight ratio, balancing performance and efficiency.
- Excellent weldability, facilitating easy fabrication.
- Widely used in construction, marine structures, and heavy machinery.

Machining
Heat Treatment
- Normalizing: Heat to 890-940°C, hold for sufficient time, then air cool to refine grain structure.
- Quenching: Heat to 880-920°C, hold, then quench in water or oil to increase hardness.
- Tempering: Reheat to 550-650°C, hold for desired time, and air cool to reduce brittleness and increase toughness.
Surface Finish
- Mill Finish: As-rolled surface without further treatment.
- Shot Blasting: Removes mill scale and improves surface texture.
- Painting/Coating: Applied for corrosion resistance, typically after blasting.
- Pickling: Acid treatment to remove scale and impurities.
- Polishing: Provides a smoother surface for specific applications.
*Customization is available upon request.
