This year, TISCO high grade stainless steel welding tape products production and sales are booming. The market development is 4 times of the same period last year, and the share in domestic high grade stainless steel welding tape market is more than 80%.

 

Stainless steel welding tape is a kind of welding material used in the manufacturing of nuclear reaction pressure vessel, petrochemical industry reaction tower, desulfurization tower, hydrogenation reactor and large-scale high temperature, high pressure and anti-hydrogen container equipment. It is generally used in building up welding process, and the aim is to form a "protective layer" in the inner wall of the container to effectively improve the corrosion resistance of the equipment and prolong the service life. Compared with ordinary composite materials, the equipment manufactured with stainless steel welding tape product has a "protective layer" which attached to the equipment body more closely, more uniform, and has better processing performance, more reliable corrosion resistance. Therefore, the stainless steel welding tape products get more and more interest from high-end equipment manufacturing enterprises, the market prospect is broad.

 

The production process of high grade stainless steel welding tape product is complex, and the rolling process is subject to crack. At present, only a few countries around the world master its core technology, which is recognized as "tough issue" in the industry. In the past, enterprises generally use small billets, narrow width production, in order to avoid cracking defects; but because of the small batch, product consistency is poor. From 2009, TISCO started to research and develop high grade stainless steel welding tape products, organized technical team to start from the basic research, conducted detailed analysis of the product composition, organizational structure and other, mastered the method to avoid crack ultimately. TISCO makes full use of the advantages of smelting technology, precise control of molten steel composition, repeatedly explores rolling parameters, so that the rolling process achieves stable control. In 2010, for the first time TISCO achieved large bloom, wide width continuous production, effectively improves consistency of the product, and TISCO became the first enterprise with the capacity of efficient large-scale production of high grade stainless steel welding tape. In 2017, TISCO’s high grade stainless steel welding tape technology once again made breakthrough. Joining hands with international top welding consumables manufacturers, TISCO collaborated with its marketing, technology, production departments, to overcome the rolling problems of stainless steel welding tape with complex composition, successfully developed ultra-difficult stainless steel welding tape products, and achieved mass production.

 

While the process and technology of TISCO’s high grade stainless steel welding tape products matures, customer satisfaction and market share keeps rising. As of now, the market development over the same period last year increased by 300%, the domestic high-end market share reaches more than 80%. The continuous progress of TISCO’s high grade stainless steel welding tape products has laid a solid foundation for development of China's high-end equipment manufacturing.
