What is S355J2G3 Steel Plate?
S355J2G3 steel plates are high-strength low-alloy structural steel plates manufactured according to EN 10025 standards. The material provides excellent toughness, weldability, impact resistance, and mechanical strength for demanding structural and engineering applications.
The “J2” designation indicates Charpy V-notch impact testing at -20°C, while “G3” refers to normalized delivery condition for improved grain structure and enhanced mechanical properties.
Triton Alloys Inc. maintains a ready stock of S355J2G3 plates in various thicknesses and dimensions with global shipping options.
