Shanghai YI HENG Special Metals Corp. Ltd. (YHSM) is located in Chongming Island, the third largest island of China. As a professional Hi-tech company, we are engaged in developing and producing the Fe-based, Ni-based and Co-based alloy. Since the establishment of our company with the original name of Shanghai Wu Zhou Special Steel Factory in 1995, we have been specialized in production of alloy with a superior combination of heat resistance and high corrosion resistance. Our products are widely used in the fields of chemical processing, aerospace engineering, marine engineering, power generation and other important industries. In 2001, we were authorized the Certification of ISO9001: 2000 Quality Management. In order to win the new competition and develop more quickly, we have launched successfully a series of reform and set up modern enterprise management system. In 2005 the old name of our company was replaced with Shanghai YI HENG Special Metals Corp. Ltd. Over more than 10 years development, we have accumulated many professional experiences in the field of producing heat-resistant alloy, corrosion-resistant alloy, precision alloy, high-quality stainless steel and obtained complete production equipments, such as Electric Arc Melting furnace, Electroslag Remelting (ESR) furnace, Forging machine, etc. After the establishment of YHSM, we purchased one ARL 3460 optical emission spectrometer from Switzerland for fast, reliable and accurate metal analysis. At the same time we built one new forging plant. In 2006 we installed a set of Vacuum Induction Melting (VIM) furnace for higher quality product. Our products mainly cover GH heat-resistant alloy, NS corrosion-resistant alloy, Hastelloy alloy, Monel alloy, Inconel alloy, Incoloy alloy and high-quality stainless steel with all standard mill forms, from large ingots and billets to plate, sheet, strip, tube, bar, wire and flange.
