The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The SA283C structural steel sheet, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
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 SA283C structural steel sheet 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.
Cleveland cliffs announced on March 13 that it had completed the acquisition of AK SA283C structural steel sheet steel, foreign media reported In the transaction of holding), shareholders of Cleveland cliffs and AK steel respectively voted on the US billion acquisition agreement at their respective shareholders' meeting to complete the resolutions required for the announcement of acquisition of AK steel SA283C structural steel sheet at the beginning of the year. The acquisition is Cleveland cliffs' first foray into steel manufacturing.
It is a modern high-tech professional enterprise integrating scientific research, SA283C structural steel sheet production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as SA283C structural steel sheet process technology development, technology transfer and related technical consulting and technical services.
