Liquefied natural gas (LNG), whose main component is methane, is a high-quality, clean, efficient and convenient "green fuel", which is considered the cleanest fossil energy in the world and one of the most important energy sources of the 21st century.
9% nickel steel is a kind of low-carbon quenched and tempered steel, containing 9% nickel element, with its excellent weldability, low cost, high strength and excellent -196 °C ultra-low temperature toughness and other advantages have become the main force in the construction of large-scale LNG storage tanks. We are committed to producing high-end welding consumables and provide supporting welding consumables and welding solutions for 9% nickel steel welding consumables as a high-quality supplier.
"Race the deer" – what makes our welding consumables stand out
Under the dual pressure of global energy and environmental issues, the LNG industry at home and abroad continues to rise. The ultra-low temperature storage conditions of LNG are a severe challenge for the host material and welding consumables. For a long time, 9% of welding consumables for nickel steel have been monopolized by imported welding consumables. In order to break the foreign technology blockade and meet the needs of LNG industry localization, we took the lead in providing a complete 9% nickel steel matching welding consumables and welding process, and stood out in the crowd with excellent product quality, professional technical team and dedicated and thoughtful service.
A full range of supporting welding consumables and welding processes are developed
All-round catering to market demand
We have designed and developed a full range of high-quality, 9% nickel steel matching consumables and welding processes, including electrodes, submerged arc wires and flux combinations, flux-cored wires for full-position welding, and argon arc welding wires. This series of products has excellent weldability and mechanical properties, and the CTOD and drop weight test results are excellent, the specific product details are shown in the table below.

"Leading the industry, blossoming everywhere" - proving strength with performance
We has been promoting the localization of welding consumables for 9% nickel-steel LNG storage tanks. Since 2016, Jingqun's 9% nickel steel welding consumables have been successfully applied to LNG marine tanks and achieved a lot of remarkable results. Subsequently, it emerged in two 50,000 cubic meter bimetallic LNG land tank projects in Changchun in 2021, and successively promoted and applied in the 200,000 cubic meter large LNG land tank project.
