quenched and tempered GL-E40 hull steel plate, No.45 seamless pipe belongs to high strength medium carbon steel, with certain plasticity and toughness, high strength and good machinability. Good comprehensive mechanical properties can be obtained by quenching and tempering treatment. In addition, the hardenability of No.45 seamless pipe is poor, and the water quenching is easy to produce cracks. After quenching and tempering, the small and medium-sized parts can obtain better toughness and higher hardness. For large parts (the section size is more than 80mm), normalizing treatment is appropriate. But the weldability of No.45 steel is poor. The weldment should be preheated before welding and annealed after welding to eliminate welding stress.
Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.
In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
We have a professional production team and high-quality production equipment, and we also have a great quenched and tempered GL-E40 hull steel plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the quenched and tempered GL-E40 hull steel plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.
Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
