EStE380 is a type of high-strength low-alloy (HSLA) structural steel plate. It’s characterized by a good combination of strength, weldability, and formability, making it suitable for various engineering applications.
Key Properties and Characteristics
- High Yield Strength: EStE380 offers a minimum yield strength of 380 MPa (Megapascals), providing excellent resistance to deformation under load.
- Good Weldability: Its chemical composition is designed for good weldability using conventional welding techniques.
- Enhanced Formability: Compared to standard carbon steels, EStE380 exhibits improved formability, allowing for easier bending and shaping.
- Improved Corrosion Resistance: While not a stainless steel, EStE380 typically offers better corrosion resistance than mild steel due to its alloy content.
Typical Applications
- Construction: Used in structural components of buildings, bridges, and other infrastructure projects.
- Heavy Machinery: Employed in the manufacturing of earthmoving equipment, cranes, and other heavy-duty machinery.
- Transportation: Found in truck frames, railcars, and other transportation equipment.
- Offshore Structures: Suitable for certain components in offshore platforms and other marine applications.
