Following up with the reliance and restructuring of Shanghai Baosteel Group Corporation and Wuhan Iron & Steel  Group Corporation, Wuhan Iron & Steel o., Ltd., subsidiary of Baoshan Iron & Steel Co., Ltd. was established on  March 2, 2017 after Baoshan Iron & Steel Co., Ltd. merged with Wuhan Iron & Steel Co., Ltd. through share  absorption, and become one of the four major production bases together with Shanghai Baoshan Steel Plant,  Nanjing Meishan Steel Plant and Zhanjiang Dongshan Steel Plant.  Located in the east of Wuhan city and to the south of Yangtze river, Wuhan Qishan steel plant has an area of 21.17  square kilometers. The plant road has a total length of 67 kilometers and the boundary of the plant is 31  kilometers. It has about 25 thousand employees so far.  Owning the complete iron and steel production process and facilities including coking, iron-making, steel-making,  steel-rolling and supporting utility facilities, the company is dedicated to the production of metallurgical products  and by products, further processing of steel products and R & D of metallurgical products.  Steel products mainly include wire rod, hot-rolled section (including hot rolled heavy rail), hot-rolled coil, hot rolled  plate, cold rolled coils and sheets, galvanized sheet (including electro- galvanized sheet), tin plate, cold rolled grain  oriented electrical steel, cold rolled non-oriented electrical steel, prepainted sheet, etc.  Through the marketing and sales network across the world, the products are widely used in automotive, home  appliance, petrochemical industry, machinery manufacturing, energy, transportation, metal products, aerospace,  nuclear power, electronic instrumentation and other industries.  As the main equipment and facilities have reached the international rst-class level, a number of products under  the four strategic categories including cold rolled electrical steel, automotive steel, high-performance engineering  structural steel and long product have gained the award of China Brand product.

Magnetic Properties The magnetic properties of the product is featured by its low core loss, high permeability and excellent application performance. Thickness Tolerance The good thickness tolerance is characterized by small difference in thickness in a direction parallel to the direction of rolling, small difference in thickness in a direction perpendicular to the direction of rolling, and high lamination factor. Processing Properties The product is suitable for punching and cutting with excellent dimensional tolerance. Insulation Coating The insulation coating has small color deviation, good adhesiveness and excellent resistance to heating and corrosion with high insulation coating resistance. There are several types of insulation coating available for production. According to the test results performed by the professional inspection organizations, the contents of hazardous substances comply with all the prevailing international and domestic environment protection laws and regulations including EU RoHS and REACH regulations.

Note: 1. Unless otherwise specied, the surface coating for non-oriented electrical steel is designated as T4 coating.  2. The self-bonding surface coating is designated as Z coating. Following the procedures of stamping and stacking, the laminations  with Z coating will be adhered by themselves after the treatment of hot pressing to assure the overall strength of the iron core. The  procedure of welding or riveting is not necessary. It must be emphasized that the electrical steel strip and sheet with self-bonding  coating shall be used within six months after ex-works.
