Our prime quality high strength structural stel plates retain the acidic attacks in tough climatic environments. These steel plates are heat-treated at very high temperatures of the heat; further, these are cold and hot workable steel. Our plates and sheets have excellent superior weldability. A572 Gr.50 dual certified plates EN10025-4 S355ML undergo many tests after the production such as corrosion test, pitting corrosion test, flattening test, flaring test, radiographic test and so on.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as en10025-4 S355ML. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.

High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of en10025-4 S355ML, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.

Since 2020, the foreign trade industry has been significantly affected by the epidemic. In the first two months of this year, China's en10025-4 S355ML and so on steel exports totaled 7.811 million tons, down 27% year-on-year, the largest decline since March 2018. In terms of steel foreign trade, China is mainly a steel exporting country, with less steel imports.
