Description
Products Description
Mechanical Properties (Thickness ≤16mm)
| Grade | Yield Strength (≥MPa) | Tensile Strength (MPa) | Elongation (≥%) | Impact Energy (Longitudinal, ≥J) |
|---|---|---|---|---|
| SN490B | 325 | 490–610 | 21 | Room temperature ≥27 |
| SN490C | 325 | 490–610 | 21 | 0℃ ≥27 |
Comparisons:
vs. Chinese Q355B: Higher tensile strength (Q355B: 470–630 MPa) but similar yield strength, suitable for structures requiring prominent tensile performance (e.g., long-span beams).
vs. European S355J0: Slightly higher impact test temperature (both S355J0 and SN490C use 0℃), but SN490C has a higher tensile strength lower limit (S355J0: 470 MPa).
Typical Application Scenarios
Building Steel Structures
High-rise frames, industrial plant beams/columns: High strength reduces steel usage and structural self-weight.
Case Study: SN490B is commonly used for core load-bearing components in Japanese high-rise buildings.
Bridge Engineering
Highway/railway bridge decks and piers: Excellent fatigue resistance for dynamic loads (e.g., vehicle traffic).
SN490C is required for low-temperature regions (e.g., Hokkaido, Japan) to meet impact resistance needs.
Marine Engineering and Port Facilities
Dock cranes, offshore platform structures: Ni and Cr enhance resistance to seawater corrosion, reducing maintenance costs.
Mechanical Manufacturing
Heavy machinery bases, mining equipment frames: Outstanding high strength and anti-deformation capabilities.
