Baosteel S235JR Low Alloy High Strength Steel Plate

General Introduction: S235JR is a type of low alloy high strength steel plate under the European standard, and Baosteel is a well - known manufacturer of such steel plates. The "S" represents structural steel, "235" indicates the minimum yield strength of 235 MPa, and "JR" denotes the quality level and impact test requirements.

Chemical Composition: It mainly contains elements such as carbon (C), manganese (Mn), silicon (Si), phosphorus (P), and sulfur (S). The carbon content is relatively low, which helps to ensure good weldability and formability. The specific composition range is C ≤ 0.17%, Mn ≤ 1.40%, Si ≤ 0.60%, P ≤ 0.035%, S ≤ 0.035%.

Mechanical Properties: Besides the minimum yield strength of 235 MPa, it has a tensile strength in the range of 360 - 510 MPa, and the elongation after fracture is not less than 26%. It also has certain impact resistance at room temperature.

Applications: It is widely used in general - purpose structural parts, such as building frameworks, bridges, and some simple mechanical equipment structures. Due to its good formability and weldability, it is easy to process and manufacture, which can meet the basic strength and stability requirements of structures.

Baosteel S355JR Low Alloy High Strength Steel Plate

General Introduction: S355JR is also a European - standard low alloy high strength steel plate, produced by Baosteel with high quality. The "S" represents structural steel, "355" represents the minimum yield strength of 355 MPa, and "JR" indicates the quality level and impact test conditions.

Chemical Composition3: The main elements include C ≤ 0.22%, Si ≤ 0.55%, Mn ≤ 1.60%, P ≤ 0.025%, S ≤ 0.025%, N ≤ 0.012%, Cu ≤ 0.55%. The appropriate content of these alloying elements effectively improves the strength and other properties of the steel.

Mechanical Properties: The minimum yield strength is 355 MPa. For plates with different thicknesses, the tensile strength is in the range of 470 - 680 MPa (for plates with a thickness ≤ 16 mm). The elongation after fracture is not less than 14%. In addition, it has good impact toughness at + 20 °C, and the impact energy is not less than 27 J.
