The company specializes in the research and development, production and sales of DIN 17100 St52-3 grade steel 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 DIN 17100 St52-3 grade steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,DIN 17100 St52-3 grade steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.

S355J2 steel plate DIN 17100 St52-3 grade steel 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 DIN 17100 St52-3 grade steel 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 Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product DIN 17100 St52-3 grade steel quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.

How much is plate DIN 17100 St52-3 grade steel per ton?
FOB Shanghai: 635$/ton
q345qd steel is steel for highway bridges, which is a thick steel plate specially used for erecting railway lines or road and highway bridges. It is required to have high compressive strength, ductility and bearing the load and impact of railway vehicles, as well as excellent fatigue relief, certain ultra-low temperature ductility and air corrosion resistance.
