Competitive price steel S690QL1 in stock

With the development of pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially in the range of large-diameter group spacing. Occupying a leading position in the field of line pipes has restricted the development of stainless steel seamless line pipes. In 2004, the output of steel S690QL1 seamless line pipes was about 400,000 tons, with steel grades including X42-70, and varieties of onshore line pipes and subsea line pipes.

Good weldabilityBecause of its low carbon content, low alloy element content, good plasticity and low hardenability, this material steel S690QL1 is not suitable to have quenching structure or crack at the weld. The cold and hot pressure processing performance is good. Because of its good plasticity and small deformation resistance, it is not easy to produce cracks after pressure processing. Good corrosion resistanceUnder various atmospheric conditions, it has higher corrosion resistance than carbon steel.

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to steel S690QL1 full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our steel S690QL1 steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.

As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another steel S690QL1 magnificent projects.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel steel S690QL1 plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
