Products Description
S235J2 is a steel grade under the European standard EN 10025. In the designation S235J2, "S" stands for structural steel, and "J2" indicates that the material has passed the -20°C impact test, with a minimum yield strength of 235 N/mm².
It is widely used in shipbuilding, engineering construction, mechanical manufacturing, and other structural applications. Alloy steel plate sizes can be customized according to client requirements, typically with thicknesses ranging from 4–120 mm, widths up to 2500 mm, and lengths cut to order.
S235J2 is a low-carbon, high-tensile structural steel that can be easily welded to other weldable steels. Its typical chemical composition includes Carbon (C) ≤ 0.17%, Manganese (Mn) ≤ 1.40%, Silicon (Si) ≤ 0.55%, Phosphorus (P) ≤ 0.035%, and Sulfur (S) ≤ 0.035%. Mechanical properties include a minimum yield strength of 235 MPa, tensile strength of 360–510 MPa, and elongation ≥ 26%, ensuring good impact toughness even at low temperatures.
The steel plate is produced using a fully killed steel process and supplied in normalized or controlled-rolled condition. Its low carbon equivalent provides excellent cold-forming properties, allowing cutting, punching, drilling, and bending operations. S235J2 is suitable for manufacturing ship structures, bridge components, industrial buildings, machinery parts, and medium-load bearing structures.

Application
S235J2 steel plate is widely used in freight cars, transmission towers, dump trucks, cranes, trailers, bulldozers, excavators, forestry machinery, railway wagons, dolphins, penstocks, pipes, highway bridges, building structures, oil and gas platforms, offshore structures, shipbuilding, power plants, palm oil equipment and machinery, fans, pumps, lifting equipment, and port facilities. Its excellent mechanical properties, good weldability, and toughness enable it to withstand medium loads and impacts in complex environments.
S235J2 steel plates are produced using a fully killed steel process and are typically supplied in normalized or controlled-rolled condition. The typical chemical composition is Carbon (C) ≤ 0.17%, Manganese (Mn) ≤ 1.40%, Silicon (Si) ≤ 0.55%, Phosphorus (P) ≤ 0.035%, and Sulfur (S) ≤ 0.035%. Mechanical properties include a minimum yield strength of 235 MPa, tensile strength of 360–510 MPa, elongation ≥ 26%, and impact toughness tested at -20°C to ensure performance and reliability in low-temperature environments.
The steel plates are available in thicknesses from 4–120 mm, widths up to 2500 mm, and lengths customized according to client requirements. They are suitable for cutting, punching, bending, and welding operations. With a low carbon equivalent and excellent cold-forming properties, S235J2 steel plates are widely applied in medium-load structural components across construction, bridges, shipbuilding, machinery, and energy industries, combining strength, toughness, and ease of fabrication.
