                The manufacturing base of Shanghai Baosteel Stainless Steel Co., Ltd., formerly known as Shanghai No.1 Iron & Steel Works, is located in the North of Changjiang Road, Baoshan District, Shanghai, covering an area of 3.4km2. In 1998, Baosteel merged and reorganized Shanghai Iron and Steel System. In 2001, a complete set of high-quality stainless steel production base for iron making, steel making, hot rolling and cold rolling, etc. was constructed at the original location. It took 10 years, with a total investment of RMB 23.5 billion, and was completed by 2010.
                The high-quality stainless steel production base is positioned in high-end stainless steel products, with joint production of high-quality carbon steel products. For the construction of this base, advanced equipments and technologies from Japan, France, Germany and other countries were introduced, integrated with the advanced steel manufacturing and process technologies of Baosteel, and the construction project won “China Construction Engineering Luban Prize”. After put into production, independent integration innovation has been persistently implemented, so that the equipment technology level is always at the leading position at home and abroad. With the application of the proprietary technologies such as stainless steel smelting in AOD with molten steel, stainless steel smelting with ultra-low carbon nitrogen ferrite, mixed rolling of stainless steel and carbon steel, hot-rolled mandrel-less hot coil box with heat shield, etc., manufacturing capability and product quality are improved comprehensively. The brand “Baosteel Stainless Steel” enjoys a good reputation in the market, the products of which have won Gold Cup Award for Physical Quality of Metallurgical Products of CISA, Special Quality Award for Physical Quality Identification of Metallurgical Products, Metallurgical Science and Technology Award and Excellent Quality Products in Metallurgical Industry of China Association for Quality and other titles. Austenitic stainless steels have been successfully applied to major construction projects such as Shanghai Tower, Shanghai World Expo China Pavilion and Guangzhou Asian Games Village. High-quality carbon steels are widely used in high-end fields such as automobiles, home appliances and containers.
                In June 2018, Shanghai Baosteel Stainless Steel Co., Ltd. was completely shut down according to the Shanghai urban overall planning and China Baowu strategic planning, and some of the existing high-quality production lines are planned to be transferred.
