Characteristics of EN10025-2 S355NL Steel Plate
Balanced High Strength and Toughness
Yield strength: ≥355 MPa (ranging from 275-355 MPa under certain standards), tensile strength: 470-630 MPa, and elongation at fracture: 21-22%.
Low-temperature toughness: Maintains specified minimum impact energy at -50°C (NL grade), making it suitable for extremely cold regions or low-temperature operating conditions.
Excellent Weldability
The reasonable proportion of carbon content and alloying elements (e.g., silicon, manganese) minimizes cracking or porosity during welding, supporting various welding processes (e.g., manual arc welding, gas metal arc welding).
Corrosion and Weather Resistance
Enhanced service life in humid or corrosive environments through the addition of chromium, molybdenum, copper, and other elements.
Fine-Grained Structure
Normalizing or normalizing rolling processes refine grain size, improve material uniformity, and ensure stable mechanical properties.
Outstanding Machinability
Supports flame cutting, laser cutting, cold bending, stamping, and other fabrication methods, with a reduction of area reaching 45-55%, meeting the demands of complex structural manufacturing.
