Low Alloy Q355B I Beams
Q355B I Beams Products Advantages
- High strength: the yield strength and tensile strength of Q355B I-beam is high, which can withstand large loads. Specifically, its yield strength is 355MPa when it is below 16mm, with the increase of thickness, the yield strength decreases gradually, but the lowest is 265MPa.
- Good weldability: Q355B I-beam has good weldability, which is easy to process and connect. In the welding process, it is necessary to choose appropriate welding methods and processes to ensure the quality of welded joints.
- Good plasticity and toughness: Q355B I-beam is able to undergo a certain degree of plastic deformation when subjected to force, thus slowing down the stress concentration and delaying the occurrence of damage. In addition, its impact toughness is also good, and can maintain stable performance in harsh environments.
- Corrosion resistance: Q355B I-beam has good corrosion resistance in some special environments. However, for long-term exposure to moisture, acids and alkalis and other corrosive environments, additional protective measures may be required.
