OREANDA-NEWS. February 18, 2011. In the year of 2010, TISCO achieved a dramatic breakthrough in duplex steel production, total development amount reach article point of ten thousand tons, which is increased 66% than it was in 2009, fully replacing imported products. The historic breakthrough marks that new products development, production process, technical management, product quality and other respects of TISCO duplex steel have rose to a new level, pioneering a new start point in domestic stainless steel industry, reported the press-centre of TISCO.
 
As a kind of stainless steel products with high technology content and high value addition, duplex stainless steel embodies the enterprise technology, equipment and management level.

In the year of 1999, according to the demand of stainless steel used for Three Gorges Project, TISCO developed S31803 (2205) duplex stainless steel, successfully applied in the clad plate production for Three Gorges Project. In 2008, "Chongqing Hao", a 9,000 tonnes (level) stainless steel chemical tanker equipped with TISCO 2205 duplex stainless steel, was smoothly launched; the inner container of its liquid cargo tank made of TISCO 2205 duplex stainless steel was the first time to adopted domestic duplex stainless steel.

In 2010, by setting market development orientation in national key project and key industries, focusing on the famous manufacturers with promising outlook and competitive strength, TISCO products widely entered the shipbuilding, nuclear power, petrochemical, and other high-end industry. Meanwhile, TISCO successfully developed S32101 duplex stainless steel new products for chemicals tanker; Cold rolled duplex steel was firstly used to decorate facades; Duplex steel of 1.5~3mm entered the desulphurization environmental protection industry.
