ST37 / S235JR Structural Steel
ST37 / S235JR 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 the complete S235 grade and product standard; ST37 alone is insufficient.
- JR, J0 and J2 carry different impact requirements; do not substitute them automatically.
Typical applications
- Welded machine frames, subject to material and welding-procedure checks.
- General structural components selected to drawing and loading requirements.
Technical selection note
Steel grades must not be considered exact equivalents based on similar names alone. Chemical composition, mechanical properties, product standard, delivery condition and heat treatment requirements must be verified against the certificate.
Salzgitter identifies S235JR / 1.0038 and the historical St37-2 reference. The source concerns flat products; its mechanical values are not universal bar properties.
