grade S690QL standard pdf

EH500 steel plates and EH550 steel plates are both ultra-high-strength structural steel plates for ships and oceans. The addition of microalloying elements can not only improve the strength, compensate for the strength loss caused by the reduction of carbon equivalent, but also improve the welding performance, mechanical properties and process performance of the steel grade S690QL. Due to the use environment requirements of EH500 steel plate and EH550 steel plate, it can meet the requirements of high strength, high toughness, high welding performance, and thickness direction performance.

What are the characteristics of medium and thick plate, grade S690QL? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, grade S690QL is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

Semi-endless rolling technology has three advantages: the grade S690QL product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.

We are engaged in grade S690QL corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, grade S690QL ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.

Both parties shall confirm the grade S690QL material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the grade S690QL steel plant.
