Recently, the Taiyuan iron and steel (Group) Company signed an order with the Ministry of Railways to make more than 20000 tons of special stainless steel plates for 3000 railway freight cars, which is an incredible order for foreign steel enterprises. The manufacture technology of the special stainless steel plate for freight cars was only mastered by a few steel mills abroad. Because of the high import price, it is useless for our country to make the railway wagons by stainless steel.

In order to grasp the manufacturing technology of special stainless steel plate of the truck, the direction of development of TISCO followed by China Railway Freight "heavy duty", with a year's time to successfully developed a special stainless steel plate truck, which is an environmentally friendly and economical steel, has the similar foreign products can not be compared with the competitive advantage in quality and the price. Experts believe that TISCO has brought a revolutionary change for the domestic railway freight car manufacturing industry.

In the successful development of the new products of TISCO, like special stainless steel plate of railway freight car, fill the high-end products, the major domestic market blank outstanding contribution to improve the level of domestic downstream manufacturing enterprises are also many, since 2003, TISCO total research and development of new products reached 432, they all have high technology content and high added value the.

In 2002, TISCO proposed the strategic goal of "building the world's most competitive steel enterprises", after years of accumulation of R & D, TISCO has formed a unique competitive advantage of strategic products, products are widely used in petroleum, petrochemical and other key areas and emerging industries. In 2005, TISCO exported 90 thousand tons of stainless steel {TodayHot}, which is expected to exceed 200 thousand tons this year.

Aiming at key technology innovation

The promotion of TISCO's product competitiveness is supported by the enhancement of independent innovation capability of enterprises. Through the original innovation, integrated innovation and the introduction of digestion, absorption and innovation, a large number of new technologies and processes with independent intellectual property rights have been formed. TISCO now has more than 700 core technologies based on stainless steel manufacturing, of which nearly 100 core technologies have international advanced level.

The nickel resources in the world, stainless steel scrap shortage, TISCO successfully developed by iron based production of stainless steel raw material technology, this technology greatly reduces the production cost of stainless steel, optimize the structure of the varieties of stainless steel, has paved the way for the development of nickel saving stainless steel.

The length of life of AOD refining furnace is a key technology link of restricting the production efficiency of stainless steel, after several years of continuous technology research, TISCO AOD furnace campaign continues to rise, from 1999 27 to 180 now, this index way ahead to other domestic stainless steel factory.

Cold-rolled silicon steel is called "the art of iron and steel materials" due to the high manufacturing technology requirements, and TISCO has a set of proprietary technology to produce high grade cold-rolled silicon steel through independent innovation.

TISCO's "high quality stainless steel plate technology development" project, "nitrogenous stainless steel production process and variety development" project respectively won the 2004 and 2005 National Science and technology progress two prize.
