Recently, TISCO's stainless steel products for automobile exhaust system passed the certification survey of Dongfeng Nissan automobile material and started to supply products to the auto producer. By getting certification from famous automobile manufacturers such as Mercedes-Benz, BMW, Toyota and General Motors, TISCO have won recognition of world-class automobile enterprises, as well as a bigger market. At present, TISCO's domestic market share of stainless steel products for automobile exhaust system exceeds 50%, and the company is one of the major suppliers of steel for automobile exhaust system in the world.
Exhaust system is an important part of automobile, which is divided into hot end and cold end. The hot end is connected with the engine, which requires excellent high temperature resistance. The cold end is connected with the tail gas purification device, which requires extremely high corrosion resistance to condensate. TISCO started the research and development of stainless steel for automobile exhaust system in 1999, and launched the first ultra-low carbon ferritic stainless steel in China in the same year. In 2004, it successfully developed the ultra-pure ferritic stainless steel that met the requirements of high-grade cold-end materials. In 2007, its stainless steel series products for automobile exhaust system passed the international quality system standard "16949", and was accepted as the designated materials by world famous automobile manufacturers such as Mercedes-Benz, BMW, Toyota and GM.
Dongfeng Nissan is publically recognized as one of the enterprises with extremely high requirements for process material selection. In 2018, TISCO passed all the surveys of Dongfeng Nissan and its assembly plant Ma Ruili, including examination on product quality, cost control, supply guarantee ability, technology research and development and management ability, and so on. And the two reached an agreement to tailor new stainless steel materials for automobile exhaust system and set special grades for Dongfeng. On this basis, TISCO Technology Center cooperated closely with relevant departments and processes, and successfully designed the material composition meeting the requirements of Dongfeng Nissan exhaust system through a series of experiments in chemical composition, mechanical properties, microstructure, corrosion resistance and high temperature. A few days ago, after trial production and application, TISCO products not only meet the exhaust emission standards and design life requirements, but also achieve the economic goals of customers, and finally become qualified materials for Dongfeng Nissan due to its advantages in stable supply, cost price, quality control, specifications and brands, and supporting services.
As an important R&D and production base of stainless steel in China, TISCO has always been committed to better meeting the market and customer needs, constantly exploring new processes and technologies of stainless steel materials, and significantly improving the physical quality and stability of products. At the same time, TISCO keeps strengthening its technical services and signing customized technical agreements with every major customers, which fully meets individual needs and continuously improves customer satisfaction.
The person in charge of related technology R&D of TISCO said that products and technologies are the foundation for enterprises to survive and thrive. We must keep in mind the general secretary's entrustment, strengthen our confidence, persevere on our career, focus on innovation, make persistent efforts to climb the peak, aim at the target of energy-saving, environmental-protection and economy-effectiveness, and constantly develop and produce more excellent stainless steel and related materials for automobile exhaust systems to help industry upgrade, and contribute for the transformation of China from a giant manufacturer in terms of quantity to a powerful manufacturer in every aspect.
