1929
The blast furnace plant of the Essen-Borbeck iron and steel mill goes into operation.
In 1917 Krupp had already built a large steel melting shop (Martinwerk 7) in Essen-Borbeck, to which a rolling mill was added in 1922/23. With the completion of the blast furnace plant, an integrated iron and steel works is formed which is among the most advanced in Europe. It becomes the center of the group's stainless steel production which is gaining importance in particular for the construction of chemical processing equipment.
Also commissioned in 1929, the 15,000 ton forging press - at the time the biggest in the world - is capable of producing high-pressure boilers from special steel ingots weighing up to 300 tons. Both plants are completely dismantled after World War Two. The undamaged steel plant is transported to the Soviet Union, the forging press to Yugoslavia.
