In 1900, British Hadfield (R.A. Hadfield) and others first discovered that Si-Fe alloy containing Si4% has good magnetic properties. In 1903, Germany and the United States successively produced hot rolled silicon steel sheets containing 1.0% to 4.5% Si. In 1906, it replaced low carbon steel and was used to manufacture motor and transformer cores. In 1934, the US Goss (N.P. Goss) used two cold rolling methods to make (110) [001] grain oriented cold-rolled silicon steel sheets containing Si3%. In 1968, Japan ’s Taguchi et al. Used a comprehensive inhibitor of manganese sulfide and aluminum nitride and used a large reduction cold rolling method to produce (110) [001] highly magnetically oriented silicon steel. The grain orientation of this material is more accurate , Iron loss and magnetic properties are further improved.

Jiangyin hengtong was found in 1989.it is a large scale , standardization, consideration, and information all constitute important factors in the development of steel managing enterprises. The company located in jiangyin city-the NO.1 of the TOP 100 cities in China ,faces the shanghai on the east and near the changjiang river on the north ,with the ascendant geographical location and convenient transportation makes goods reach to destination very quickly.

Now we have two companies, jiangyin hengtong ,jiangsu smart motor technology（jiangsu shuaijin） ,about 200 employees ,30% of them is professional and technical talents.jiangyin hengtong is as a window of the group . it got the ISO9001 ROHS SGS ISO14001 IATF16949 and the horner of jiangyin high-tech enterprise,jiangyin key enterprise . it covers about 1300 are and has two set of slitting machine , twelve sets of annealing equipment .more than 50 sets of punching machine and cutting machine. We can produce most of kinds EI type ,UI type and other silicon steel sheet in the market ,Contain the thickness 0.23mm 0.30mm 0.35mm 0.5mm etc .annual quantity is about 50000 ton.

In the past 20 years, jiangyin hengtong made a great achievement in the filed of transformer industry , Power tools industry, household appliances industry, welding industry, automobile manufacturing industry .well-known and trust by the domestic and foreign enterprises ,such as microtek ,luminous , leader,EAGTOP,GREE etc. The products has been sold to US, Brazil ,India ,EGYPT,RUSSIA AND POLAND. Jiangyin hengtong has been the most important punching company in the word .
