DIN 17100 St52-3 Steel Plate | St52-3 Structural Steel
What is DIN 17100 St52-3 Steel Plate?
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present DIN 17100 St52-3 Steel Plate.
St52-3 is a high-strength non-alloy structural steel under the former German standard DIN 17100. It provides a minimum yield strength of 355 MPa (for thickness ≤ 16 mm) and a tensile strength range of 510–680 MPa. This grade is one of the most widely used high-strength structural steels from the old DIN series and is essentially equivalent to modern EN 10025-2 S355J2 / S355J0. It offers a good combination of strength, toughness and weldability.
This grade belongs to the DIN 17100 Steel Plate series. SHH STEEL supplies St52-3 as Mill Direct Supply, sourcing directly from major Chinese steel mills. This ensures competitive mill pricing, consistent quality, shorter lead times and full traceability. We offer thicknesses from 6 mm to 150 mm, widths up to 3000–4000 mm and lengths up to 12000–18000 mm. Custom cutting, shot blasting and priming services are available. All plates are delivered with full Mill Test Certificates (EN 10204 3.1 or equivalent).
