Cause analysis of cracks in EN steel grade S235J2 plates

EN steel grade S235J2 plates, Q345D seamless pipe is low-alloy high-strength structural steel. It is named as low-alloy because of a small amount of alloy elements in the steel. Q345D seamless pipe is mainly used for construction and engineering structures. The carbon content of Q345D seamless pipe is ≤ 0.18%. Due to the effect of alloy elements, the yield strength of Q345D seamless pipe is 25% - 150% higher than that of carbon structural steel pipe with the same carbon content. Q345D seamless pipe can reduce the weight of steel structure, save steel products and effectively extend the service life of steel structure.
