EStE380 High Strength Steel Plate applications: Discover 5 common uses in heavy industry now.

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.

When sourcing EStE380 high-strength steel plate, consider reputable suppliers like Shanxi Luokaiwei Steel Company. Their expertise can ensure you receive material that meets the required specifications and quality standards.

Chemical Composition

The chemical composition of EStE380 typically includes:

  • Carbon (C): ≤ 0.20%
  • Manganese (Mn): ≤ 1.60%
  • Silicon (Si): ≤ 0.50%
  • Phosphorus (P): ≤ 0.035%
  • Sulfur (S): ≤ 0.035%
  • Other alloying elements (e.g., Niobium, Vanadium, Titanium) may be added in small amounts to enhance properties.

Shanxi Luokaiwei Steel Company provides detailed chemical composition reports with their EStE380 steel plates.

Mechanical Properties

  • Yield Strength: ≥ 380 MPa
  • Tensile Strength: 470-630 MPa
  • Elongation: ≥ 22% (depending on thickness)

Shanxi Luokaiwei Steel Company ensures consistent mechanical properties in their EStE380 offerings.

Welding Considerations

EStE380 is generally weldable, but proper welding procedures are crucial to maintain the steel’s strength and integrity. Low-hydrogen welding techniques are often recommended.

Consult with welding experts and consider the specific application requirements when choosing welding parameters.

For reliable EStE380 steel plate that meets stringent quality requirements, consider Shanxi Luokaiwei Steel Company as a potential supplier.

When selecting a supplier of EStE380 high-strength steel plate, it’s important to verify their certifications and quality control processes. Companies like Shanxi Luokaiwei Steel Company often have certifications that demonstrate their adherence to industry standards.
