Products Application
S355JR is a low-alloy high-strength structural steel that meets the EN 10025-2 standard, with a minimum yield strength of 355 MPa, a tensile strength of 470–630 MPa, and an elongation of ≥ 20%, ensuring excellent toughness and stability under heavy loads and dynamic impacts. Its good weldability and machinability make it an ideal material for heavy engineering and machinery applications.
Transportation and Heavy Machinery
S355JR steel plate is widely used in the main structural components of freight cars, trailers, dump trucks, bulldozers, excavators, cranes, and forestry machinery. Its high strength and toughness ensure safety and reliability under long-term operation and high load conditions.
Infrastructure and Bridge Engineering
It is also used in highway bridges, railway wagons, and dolphin structures. Its impact resistance and high strength guarantee that bridges, docks, and railway structures remain stable even under extreme loads and harsh weather conditions.
Energy and Offshore Engineering
In power transmission towers, power plants, oil & gas platforms, and offshore structures, S355JR plates are applied to load-bearing frames, supports, pipelines, and penstocks. Excellent weldability and ductility allow for complex welded structures while ensuring long-term service safety.
