xar 400 steel plate H beams
EN10025-2 S355K2 is a non-alloy steel quality with 355Mpa minimum yield strength when thickness ≤16mm. It takes low temperature impact testing at -20℃ with minimum energy 40J. For the advantage of S355K2 steel plate, xar 400 steel plate, it offers good weldability with conventional welding processes. In addition to their good mechanical properties, structural steels also have very acceptable toughness values. S355K2 steel plates are widely used in low temperature surroundings such as ice river, deep oceans.
The company specializes in the research and development, production and sales of xar 400 steel plate 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 xar 400 steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,xar 400 steel plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
During the construction of hot-dip xar 400 steel plate galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the xar 400 steel plate construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
The characteristic of niobium in xar 400 steel plate etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
