Applications of JIS G3114 SMA490AP Steel
Bridge Engineering
Main Girders and Crossbeams: Its high strength and fatigue resistance support static and dynamic loads in large-scale bridges, while weather resistance reduces anti-corrosion maintenance costs.
Case Study: Multiple sea-crossing bridges in Japan utilize SMA490AP, maintaining structural stability despite prolonged exposure to salt spray environments.
Building Structures
High-Rise Building Frames: The narrow yield strength fluctuation range (≤0.80 yield ratio) ensures uniform deformation, absorbing seismic energy and enhancing earthquake resistance.
Factory Steel Columns: Delivered in hot-rolled condition, it facilitates easy cutting and bending, offering cost-effective and efficient processing.
Vehicles and Ships
Ship Decks: High tensile strength withstands wave impacts, while weather resistance reduces rusting and extends service life.
Railway Vehicles: Exceptional weldability supports automated production, improving manufacturing efficiency.
Energy Facilities
High-Pressure Water Pipes in Hydropower Stations: High-temperature strength and creep resistance ensure safe operation under high-pressure conditions.
Oil Storage Tanks: Corrosion resistance minimizes the risk of oil leakage, meeting environmental protection requirements.
