Primetals Technologies Limited, is an engineering and plant construction company for clients in the metals industry, both the ferrous and the nonferrous metals sector.[2][3] The firm, based in London (UK), is a joint venture established in 2015 by bringing together Siemens VAI Metals Technologies and Japan’s Mitsubishi Hitachi Metals Machinery (MHMM).[4]

Mitsubishi Hitachi Metals Machinery (MHMM), an MHI consolidated group company with equity participation by Hitachi, Ltd. and IHI Corporation, holds a 51 percent stake and Siemens a 49 percent stake in the joint venture. The combined company has some 7,000 employees worldwide.


Through its owners, Siemens and Mitsubishi Heavy Industries (MHI), Primetals Technologies can draw on almost 170 years of experience. Its expertise covers the entire value chain in iron and steel production, thanks to the many acquisitions made during this time. The most significant invention remains the BOF (LD) process, which is now used in more than 70 percent of steel works worldwide. Other significant processes are Corex and Finex, which rely on the direct use of coal to produce pig iron.
