In the late 1840s, the German chemist Franz Anton Lohage developed a modification of the puddling process to produce not iron but steel at the Haspe Iron Works in Hagen; it was subsequently commercialized in Germany, France and the UK in the 1850s, and puddled steel was the main raw material for Krupp cast steel even in the 1870s.

en.wikipedia.org/wiki/Puddling_(metallurgy)Puddling was the first successful process for making malleable iron from pig iron without using charcoal. Unlike in the Finery the iron was not in direct contact with the fuel of a puddling furnace, only with the hot gases from it. This helped reduce the amount of impurities in the finished iron.
www.culturenlmuseums.co.uk/story/puddlers-shingl…The original dry puddling process was replaced beginning in 1830 by wet puddling, which was radically different in terms of the key chemical reactions involved, the thermal behaviour of the melt, the speed of the process and the quality and consistency of the resulting product.
hmsjournal.org/index.php/home/article/view/169Puddling steel is a technique with which pig iron in semi-melting state can be puddled and decarbonized into steel. It is a steelmaking technique in ancient China. During the process, pig iron is first heated in the air to the semi-melting state.
link.springer.com/referenceworkentry/10.1007/978-…steel was “puddling” of cast iron. A major development of the process, “wet puddling”, became wide-spread commercially beginning in 1830. That process is examined quantitatively using modern thermody-namic, solidification and rheologic understanding. The ‘clearing’ and ‘boiling’ steps are considered in detail.
