S235JR Non-Alloy Structural Steel Plate Under EN 10025-2 Standard

​S235JR is a non-alloy structural steel plate that conforms to the EN 10025-2 standard, widely recognized and used globally for its reliable mechanical properties and versatile applications. This article provides a comprehensive introduction to S235JR steel plates, covering their chemical composition, mechanical properties, heat treatment status, low-temperature impact testing, available dimensions, primary application scenarios, and supply cases by TJC Steel Group.
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.
Available Dimensions
S235JR steel plates are available in a wide range of dimensions to meet various application needs. The thickness can vary from a few millimeters to hundreds of millimeters, while the width and length can be customized according to customer requirements. Common thicknesses include 12mm, 14mm, 16mm, and more, with lengths and widths typically in the range of 2500mm to 12000mm.
Primary Application Scenarios
Due to its good mechanical properties, welding performance, and processing performance, S235JR steel plates are widely used in various industries. Primary application scenarios include:
Structural components of buildings and bridges
Machinery and equipment parts
Shipbuilding and automotive industry
Manufacturing tools, dies, molds, and gauges
Logistics and warehousing systems, such as racks and shelves
