"Wales has long been a global leader in steel innovation, with many of the industry's giant leaps forward taking place here: the Bessemer process, pioneered in Dowlais and Ebbw Vale; the Siemens open-hearth process, first demonstrated in Swansea; the Gilchrist-Thomas Basic process, based on work in Blaenavon; and the pioneering Abbey Works at Port Talbot, opened in 1951."
The open-hearth process, which had begun to replace the Bessemer converters earlier in the century, was hard-pressed to provide steel in sufficient quantity and quality for the automotive industry.
