Antai San Ying is vigorously building a research and pilot-testing base for welding materials at China Iron & Steel Research Institute, paving the way for high-quality development!
Antai San Ying Welding Materials
(Tianjin) Co., Ltd.
It is a strategic business unit under China Iron and Steel Research Institute Group Antai Technology Co., Ltd., tasked with the mission of a central state-owned enterprise and deeply rooted in the field of welding materials. Since its establishment in 1994, the company has grown into a professional manufacturer with two well-known brands—“Antai Welding Materials” and “Sanying Welding Industry”—and has achieved synergistic development through a dual-brand strategy.
Relying on the robust technological support provided by the Institute of Iron and Steel Research, Antai Technology, and Tianjin University, the company has built a high-level research team and established a comprehensive industrialization system. Focusing on national strategic needs, Antai San Ying leverages innovative welding material technologies to empower major infrastructure projects and accelerate the localization of critical materials. In the fields of shipbuilding and marine engineering, the company is the first domestic enterprise to achieve localization of flux-cored wires for structural steel and stainless steel, continuously providing key technological support in areas such as carbon steel, low-temperature steel, and high-strength steel flux-cored wires. In the energy and chemical industries, as one of the first domestic companies to successfully localize special welding materials for boiler and pressure vessel applications, the company’s product series fully meet the manufacturing requirements for petrochemical equipment, boiler and pressure vessels, and even critical components for nuclear power plants. In the field of super-engineering projects, the company’s developed product series have been successfully applied to nationally iconic projects.
