Nippon Steel's Wakayama plant is based in Wakayama prefecture. The plant was part of Sumitomo Metals Industries before the company's merger with Nippon Steel Corporation in October 2012 to form Nippon Steel & Sumitomo Metals Corporation (NSSMC). NSSMC has since been renamed to Nippon Steel. The Wakayama works specialises in the manufacture of high end seamless steel pipe and tube products that are used in the oil and gas sector. The plant is also a producer of cold rolled sheet, galvanised and electrical steel sheet and stainless steel.
