QStE500TM automobile steel plate,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 Gr50 dual certified plates undergo many tests after the production such as corrosion test, pitting corrosion test, flattening test, flaring test, radiographic test and so on,QStE500TM automobile steel plate.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
