DIN 17100 ST52-3 steel plate is a low-carbon high-strength structural steel widely used in the global heavy engineering and construction industries. ST52-3N denotes the normalized delivery condition, while ST52-3 is normally supplied in normalized or controlled-rolled state.
Thanks to its low carbon equivalent, ST52-3 offers good cold-forming and welding performance, making it a preferred choice for heavy-load structural components across many industrial sectors. We keep abundant spot stock and provide custom cutting, processing and third-party inspection.

The ST52-3 designation encodes the steel family, strength class, quality grade and delivery condition under DIN 17100.
The leading letters identify the material as a general structural steel for engineering use.
Indicates a tensile strength class of about 520 MPa (52 kgf/mm² nominal).
Quality grade 3 denotes charpy impact-tested structural steel for better toughness.
ST52-3N is supplied in normalized condition for stable and uniform mechanical properties.
Low carbon equivalent gives excellent cold-forming and welding performance.
Normally supplied normalized or controlled-rolled; ST52-3N is the normalized variant.
ST52-3 is a low-carbon structural steel with the following heat-analysis composition limits (maximum %), per DIN 17100.
| Grade | C (max) | Si (max) | Mn (max) | P (max) | S (max) | Ceq (max) |
