Manganese (Mn): ≤1.5%
Phosphorus (P): ≤0.045%
Sulfur (S): ≤0.045%
Nitrogen (N): ≤0.0090%
Iron (Fe): ≥98.2%
Characteristics of S275JR c channel bar
Good strength: The yield strength is above 275MPa, which can withstand large loads and is suitable for structures with certain strength requirements.
Good weldability: It can be easily welded with other steel components using common welding methods, and the performance of the welded joint is good, which can ensure the integrity and reliability of the structure.
Strong plasticity and good toughness: good deformation ability, can effectively resist impact and vibration loads under external force, and is not easy to crack.
Good formability: can be processed into various shapes and sizes through bending, rolling and other processes to meet the needs of different engineering designs.
