What should be paid attention to when using SA283 Grade C, S355JR, S355N mild steel section, carbon steel? First, the strength level of carbon steel is low and it is easy to fracture, so carbon steel is not suitable for high strength engineering. Second, the heat-resistant performance of carbon steel is relatively poor, which can not be applied in the long-term high-temperature fields such as boilers. Third, the carbon steel is extremely easy to rust, so it is not suitable for water transport projects. Therefore, the use of carbon steel depends on the use of the environment, if it is harsh conditions, it is better to choose other steel materials.
SA283 Grade C, S355JR, S355N mild steel section, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
