Cause analysis of red oxide iron on S690QL quenched and tempered material surface

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld S690QL quenched and tempered material steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for S690QL quenched and tempered material manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and S690QL quenched and tempered material steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to S690QL quenched and tempered material customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.

The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.
