The welding technology of S690QL plate

BBNSteel served SA 516 GR 70 boiler quality plates to many industries like oil, gas, petrochemicals and because of having a high demand for sa516 Grade 70 boiler steel plates by our worldwide clients. We ensure that the S690QL plate material is always in stock and available to you from our warehouse. So we always make sure to provide all the ordered products on time with our big delivery network.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, S690QL plate based on a high starting point and high technology, the company has vigorously developed various steel products S690QL plate and deep-processed parts, steel structures, precision castings, seamless pipes.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled S690QL plate products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the S690QL plate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to S690QL plate, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
