Equivalent and Applicant Field
01.Equivalent :
| Standard | Grade | Equivalent basis |
| GB/T 700 | Q235B | Yield ≥ 235 MPa, tensile strength 370-500 MPa, P/S ≤ 0.045%, pay attention to differences in toughness and temperature impact |
| ASTM A36/A36M | A36 | Yield ≥250MPa, tensile strength 400-550MPa, stricter manganese content requirements, consistent welding performance, mainstream substitute in North America |
| EN 10025-2 | S235JR | Yield strength ≥235 MPa, tensile strength 360-510 MPa, carbon content ≤0.20%, suitable for European projects, with specific requirements for impact energy |
| DIN 17100 | ST37-2 | Yield strength ≥235 MPa, tensile strength 360-510 MPa, performance basically consistent with S235JR |
02.Applicant Field:
- Building structures: Beams, columns, floor slabs, and stairs in factories, residential, and commercial buildings, as well as load-bearing components such as bridge railings, bridge piers, and bridge decks.
- Mechanical manufacturing: Light machinery bases, bearing supports, gearbox housings, agricultural machinery brackets, and general welded parts, suitable for bending, stamping, welding, and other processing.
- Transportation: Vehicle chassis, frames, truck body panels, non-critical ship structural components (such as bulkheads and supports), container frames, and trailer chassis.
- Other fields: Power transmission towers, communication towers, scaffolding, pipe supports, small pressure vessels (non-high-pressure), municipal guardrails, and other general structures.
