Delamination damage of S690QL steel equivalent to grade 50

The company now has S690QL steel equivalent to grade 50 oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than S690QL steel equivalent to grade 50 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Q345qCNH grade is a weather-resistant structural steel for bridges. Bridge steel grade is Q345qC. It is produced by the standard GB / T714-2014. Weather-resistant bridge plate Q345qCNH is a kind of structural steel plate for bridge. Add a certain amount of alloy elements, such as P, Cr, Ni, Cu, Mo, etc. to the steel to form a protective layer on the surface of the metal substrate to improve the atmospheric resistance corrosive steel.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of S690QL steel equivalent to grade 50, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.
