GL-F40 hull steel plates fast delivery to Asia

Boiler steel plates are mainly used to manufacture various boilers and important accessories. Because the boiler steel plate is working under medium temperature (below 350°C) and high pressure, in addition to high pressure, it is also subject to impact, fatigue load and water and gas corrosion. It is required to ensure a certain strength and also have good welding and cold bending performance. Common grades: Q245R, A515 Grade 55, A515 Grade 60, GL-F40 hull steel plates, A516 Grade 65, A516 Grade 70.In recent years, in line with the development trend of iron and GL-F40 hull steel plates steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which GL-F40 hull steel plates are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.S355J2 steel plate GL-F40 hull steel plates rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the GL-F40 hull steel plates single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.The steel such as GL-F40 hull steel plates delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades.
