Introduction to EN10025-2 S275J0 Non-Alloy Structural Steel Plate

The EN10025-2 S275J0 non-alloy structural steel plate is a premium material renowned for its strength, ductility, and versatility across various engineering applications. Produced and inspected according to the stringent European standard EN10025-2, this steel plate offers a combination of mechanical properties and chemical compositions that make it ideal for numerous structural purposes.
Chemical Composition:
The S275J0 steel plate is primarily composed of iron, with key alloying elements including carbon (C), silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S). The specific chemical composition ensures excellent weldability and processability. The carbon content enhances hardness and strength, while manganese and silicon improve toughness and corrosion resistance. The phosphorus and sulfur contents are carefully controlled to maintain the overall quality and performance of the steel.
Mechanical Properties:
The mechanical properties of S275J0 steel plate are impressive, with a minimum yield strength of 275 MPa. The tensile strength ranges between 430-580 MPa (alternatively specified as 430-550 MPa), providing stability and reliability under heavy loads and stress. These properties, coupled with good elongation and impact resistance, make S275J0 suitable for a wide range of structural applications.
Heat Treatment State:
S275J0 steel plates are typically delivered in hot-rolled, controlled rolled, or normalized conditions. The heat treatment process optimizes the mechanical properties and ensures consistent quality across the plate.
Low-Temperature Impact Testing:
S275J0 steel plates undergo rigorous low-temperature impact testing to assess their resistance to brittle fracture in cold conditions. The material maintains good impact toughness at 0°C, as denoted by the 'J0' suffix, ensuring safe performance in low-temperature environments.
