Low Alloy S355JR I Beams
S355JR I Beams Products Details
- Chemical composition: contains a certain amount of alloying elements, such as manganese (Mn), silicon (Si), etc. These elements help to improve the strength, toughness, corrosion resistance and wear resistance of the steel plate.
- Physical properties: NMness is usually between 70-80B, yield strength of 355MPa minimum, the actual yield strength between 300-400MPa, high tensile strength.
S355JR I Beams Products Advantages
- High strength: the yield strength of S355JR I-beam reaches 355MPa, with high tensile strength and yield ratio, it is able to withstand various complex loads and stresses.
- Good toughness: When subjected to shock or vibration, S355JR I-beam can maintain its shape and performance, and the impact toughness under 20°C can reach 27J.
- Excellent welding performance: S355JR I-beam is easy to carry out a variety of welding processes, such as manual arc welding, submerged arc welding, gas shielded welding, etc., which makes it very popular in the fabrication of structural components that require welded connections.
- Good processability: S355JR I-beam steel not only has good cold working performance, but also has excellent hot working performance, easy to cut, bend, molding and other processing operations.
- Good corrosion resistance: In general atmospheric conditions, S355JR I-beam has good corrosion resistance, which can extend the service life of structural components and reduce maintenance costs.
