The stainless steel products for automobile exhaust systems produced by China Special Steel TGJT Group passed the certification of Shanghai General Motors and began to supply. This is the product of TGJT, which has been recognized by world-class car companies after the certification of Mercedes-Benz, BMW, Toyota and other well-known auto manufacturers, further expanding the market space. At present, TGJT's stainless steel products for automobile exhaust systems occupy the first domestic market share, and it is one of the world's major suppliers of automotive exhaust system steel.
The automobile exhaust system is an important part of the car, which is divided into two parts, the hot end and the cold end. The hot end is connected to the engine and requires good high temperature resistance. The cold end is connected to the exhaust gas purification device and requires extremely high resistance to condensation corrosion. TGJT has been involved in the research and development of stainless steel for automobile exhaust systems since 1999, and it is the first domestic ultra-low carbon ferritic stainless steel. In 2004, we successfully developed ultra-pure ferritic stainless steel to meet the demand for advanced cold-end materials. In 2007, TGJT's stainless steel products for automotive exhaust systems passed the internationally accepted automotive industry quality system standard "16949" certification, and have become the designated materials for Mercedes-Benz, BMW, Toyota and other world-renowned auto manufacturers.
GM is recognized in the industry as one of the most demanding companies for process selection. In 2017, TGJT and Shanghai GM reached an agreement to specifically "tailor" new stainless steel materials for automotive exhaust systems for the company. After nearly two years of hard work, with the close cooperation between TISCO Technology Center and various departments and processes, a material composition system that meets the requirements of GM exhaust systems has been successfully designed. After trial production in small batches, the product not only fully meets the exhaust Emission standards and design life requirements, and achieved the customer's economic goals, eventually becoming a qualified material for GM. At the same time, TGJT also used GM's strong market guidance to further open up the development space for stainless steel materials for automotive exhaust systems. In September 2019, TGJT, together with Pan Asia Automotive Technology Center Co., Ltd. and Shanghai Tenneco Exhaust System Co., Ltd. jointly established a joint laboratory for stainless steel for automobiles, and jointly promoted the development and application of new stainless steel materials for automotive exhaust systems. Upgrading of related traditional materials.
As an important domestic stainless steel R & D and production base, TGJT is always committed to better meeting the market and customer needs. With the continuous improvement of environmental protection requirements, major automobile manufacturers are paying more and more attention to the manufacturing level of automobile exhaust systems, and the performance requirements of related materials are becoming more and more demanding. In recent years, based on years of accumulation, TGJT has continuously explored new processes and technologies for stainless steel materials for automotive exhaust systems, and the physical quality and stability of its products have been significantly improved. At the same time, TGJT strengthened technical services and signed "one household, one volume" technical agreements with major automobile manufacturers and supporting enterprises, fully satisfying the individual needs of customers and increasing customer satisfaction. Product market development volume exceeds 300,000 tons.
