A572 Gr 55 ms steel coil, Q690CF steel plate, also known as CF (CrackFree) steel in the world, is a kind of steel with low carbon equivalent, low PCM value and excellent welding function. It is generally believed that there is no crack in welding without preheating or under low preheating conditions. In order to further improve Q690CF steel strength, TMCP and microalloying skills are also required.
The qualified flat steel has sufficiently high high temperature strength and high temperature plasticity. Therefore, A572 Gr 55 ms steel coil flat steel is not only required to have high enough normal temperature and instantaneous high temperature tensile strength and plasticity, but also long-term strength and long-term plasticity to ensure long-term safe work at high temperatures, especially under creep leakage conditions. The product thickness is 8-50mm, width 150-625mm, length 5-15m。
The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the A572 Gr 55 ms steel coil and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.
