S690QL1 ASTM equivalent mild steel sheet coils

S960QL grade is a European standard special alloy structural steel, which belongs to quenched and tempered high yield strength structural steel. S indicates structural steel, 960 is a yield value, in MPa, Q indicates delivery conditions, and L indicates that the impact energy is specified when the temperature is not less than -50℃ The smaller value of. S960QL steel plate is a material in the European standard EN 10025-6.

ArcelorMittal USA said S690QL1 ASTM equivalent it was planning to work with the United Steelworkers union "to minimize the impact on its employees. The company will continue to communicate with its customers to understand the market impact of the outbreak of covid-19, which may require additional capacity optimization to maintain a balance between supply and demand.

How to prevent S690QL1 ASTM equivalent, steel plate cutting cracks? 1. Preheat the steel plate before cutting, and the preheating temperature depends on the quality grade and thickness of the steel plate. However, it needs to be heated evenly. 2. The cutting speed is reduced appropriately, but its reliability is not as good as preheating. It is suggested to preheat the cutting belt with flame gun cavitation several times before cutting, and the preheating temperature should reach about 180℃.

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 S690QL1 ASTM equivalent 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.
