How to avoid the pits on the surface of S690QL1 1.8988 high strength steel sheet

Shipbuilding steel plates or offshore platform plates are used to make hulls, offshore oil production drilling, platform pipe joints and other structural parts; Our ship steel plates are nine classification societies certified( American ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, South Korea KR ). S690QL1 1.8988 high strength steel sheet, These plates can be Z15 / Z25 / Z35. Our company stocks a large number of shipbuilding plates, S690QL1 1.8988 high strength steel sheet, offshore platform plate steel in stock.

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional S690QL1 1.8988 high strength steel sheet production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of S690QL1 1.8988 high strength steel sheet leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of S690QL1 1.8988 high strength steel sheet high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's S690QL1 1.8988 high strength steel sheet technical equipment.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for S690QL1 1.8988 high strength steel sheet and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

Our quality and service commitment: S690QL1 1.8988 high strength steel sheet product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
