Chemical Composition The chemical composition of S235JR steel plates is precisely controlled to ensure consistent quality and performance. The typical chemical elements and their permissible ranges are as follows: Carbon (C) ≤ 0.17% (or ≤ 0.22% in some specifications), Silicon (Si) ≤ 0.35%, Manganese (Mn) ≤ 0.65% (or up to 1.70% in some cases), Phosphorus (P) ≤ 0.030% (or ≤ 0.045%), and Sulfur (S) ≤ 0.030% (or ≤ 0.045%). Mechanical Properties S235JR steel plates exhibit excellent mechanical properties, making them suitable for various structural applications. The minimum yield strength is 235 MPa, while the tensile strength ranges from 360 to 510 MPa. The elongation at break is typically ≥18%, indicating good ductility. Additionally, the impact absorption energy at 0°C is required to be not less than 27J, ensuring material toughness under low-temperature conditions. Heat Treatment Status S235JR steel plates are generally supplied in the as-rolled condition, which means they have undergone hot rolling and may be followed by normalizing or stress-relieving annealing if necessary. The as-rolled condition provides a balance between strength, ductility, and weldability, making it suitable for most structural applications. Low-Temperature Impact Testing Low-temperature impact testing is conducted to assess the material's toughness at sub-zero temperatures. S235JR steel plates meet the impact energy requirements at 0°C, with a minimum impact absorption energy of 27J. This ensures that the material can withstand sudden loads and impact without brittle fracture in cold environments.
