What are the methods of S690Q material cutting

What are the general uses of S690Q material, low alloy steel plate? First, low alloy steel plate can be used as bridge steel plate, because it has strong bearing capacity. The bridge’s daily traffic flow is very large, so it must have very good bearing capacity. Second, because low alloy steel plate has good toughness and is easy to process, it is often used to manufacture ships and vehicles. Thirdly, the use of low alloy steel plate is indispensable to the construction of some frame structure workshops. Because of the low alloy content, low alloy steel plate has its own characteristics.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < S690Q material steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished S690Q material product packaging.

Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our S690Q material products have a high visibility and market share at home and abroad. At the same time, we will always bear the principle of "credit first, customer first", always put the interests of customers first, and wholeheartedly provide each of our customers with the best products and services.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S690Q material EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
