The Krupp steelworks, or Krupp foundry, or Krupp cast steel factory (German: Krupp-Gussstahlfabrik [Guss+stahl+fabrik]) in Essen is a historic industrial site of the Ruhr area of North Rhine-Westphalia in western Germany that was known as the "weapons forge of the German Reich" (Waffenschmiede des Deutschen Reiches).
Krupp Steel Works of Essen, Germany, manufactured the spherical pressure chamber of the dive vessel Trieste, [14] the first vessel to take humans to the deepest known point in the oceans, accomplished in 1960. This was a heavy duty replacement for the original pressure sphere (made in Italy by Acciaierie Terni) and was manufactured in three ...
The Krupp night decoy site Kruppsche Nachtscheinanlage was a German decoy-site of the Krupp steelworks in Essen. It was designed to divert Allied night airstrikes in the bombing of Essen in World War II from the actual production site of the arms factory.
Krupp took over production, including at the Molotov steel works near Kharkov and Kramatorsk in eastern Ukraine, and at mines supplying the iron, manganese, and chrome vital for steel production. The battle of Stalingrad in 1942 convinced Krupp that Germany would lose the war, and he secretly began liquidating 200 million Marks in government bonds.
ThyssenKrupp is the result of a merger of two German steel companies, Thyssen AG founded in 1891 under the name Gewerkschaft Deutscher Kaiser and Krupp founded in 1811. As early as the 1980s, the companies began negotiations on a merger and began closely cooperating in some business areas.
The Krupp steelworks was one of the few companies capable of making crucible steel.It used this cast steel to make castings from which steel gun barrels were forged. [3] In the 1860s, Krupp's ability to make the big high quality casts required for big guns was unique.
During the 1980s, talks on a merger between Thyssen Stahl AG and Krupp Stahl AG took place. An alliance did not take place at that time, but there began cooperation on certain business areas (tinplate, electrical steel, and stainless steel). [1] In 1997, the flat steel production divisions of both groups were merged to form Thyssen Krupp Stahl AG.
At the Krupp steelworks, this led to expanding the Ring Kanonen system with the 30.5 cm RK L/22 and the 35.5 cm MRK L/22.5 coastal gun. [7] The change from the Ring Kanone construction to the stronger barrels of the Mantel Ring Kanone started in 1875. [8] It led to the 30.5 cm MRK L/22, which was problematic at first.
