Improvement measures of layered fracture in steel plates S690QL tension

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, steel plates S690QL based on a high starting point and high technology, the company has vigorously developed various steel products steel plates S690QL and deep-processed parts, steel structures, precision castings, seamless pipes.

As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.

The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, steel plates S690QL is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.

In October 19th 2018, our Malaysia customer purchased 600 Tons CCS Grade AH36 mairne steel steel plates S690QL plates to use in their shipbuilding project .This customer is a famous shipyard company in Malaysia. Their company has the business scope of tourism, shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality for CCS Grade AH36 mairne steel plates. After visiting our steel milll, the customer is very satisfied with the quality of this batch of CCS Grade AH36 steel plates.

The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, steel plates S690QL.

The company focuses on quality building, continuously create greatest value for customers, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, perfect sales services, strict quality purchase management system and science overall marketing means. We are willing to go hand in hand with you for common development. To be the best service provider for iron & steel products globally is our goal.
