The S690QL steel suppliers, wear-resistant steel plate has complete specifications and many varieties, and has become a commercial series. The thickness of the wear-resistant alloy layer is 3-20mm. Wear-resistant steel plates are divided into three types: ordinary type, impact resistant type and high temperature type. Wear-resistant steel plate can be cut, bent or crimped, welded and punched, and it can be processed into various parts that can be processed by ordinary steel plate. The cut wear-resistant steel plates can be tailor-welded into various engineering structural parts.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S690QL steel suppliers EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
