ST52 / S355 / S355J2 Structural Steel
ST52 / S355 / S355J2 Structural Steel is supplied for mechanical engineering and serial production applications where the grade, delivery condition, dimensional tolerance and traceability must be specified together. Erkal Haddecilik supplies cut-to-length steel from Bursa subject to stock.
Key properties
- Specify S355JR, S355J0 or S355J2; impact requirements are part of grade selection.
- Historical ST52 terminology does not replace the full product standard and delivery condition.
Typical applications
- Load-bearing machine frames checked against section and design requirements.
- Welded structural components with specified impact and welding requirements.
S355J2 has material number 1.0577 under EN 10025-2. Number 1.0570 relates to historical St52-3 / DIN 17100. Verify substitution against the product standard, delivery condition, impact requirements and certificate.
ST52 / S355 / S355J2 steel: designation and ordering
ST52 is an older or commercial designation, while S355 names a grade family. S355JR, S355J0 and S355J2 are not a single undifferentiated purchase description; retain the exact suffix and required delivery condition.
For frames and load-bearing parts, provide the drawing standard, product form, section and impact requirements. Confirm the certified grade rather than ordering “ST52” alone.
