A514 grade B steel material normalized and impact tested plate

Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons A514 grade B steel material products have been directly supplied to European customers.

The company specializes in the research and development, production and sales of A514 grade B steel material seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A514 grade B steel material five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A514 grade B steel material rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

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 A514 grade B steel material 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 A514 grade B steel material rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of A514 grade B steel material etc. steel material.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
