Quality Forgings - Made in Germany Dirostahl or Karl Diederichs KG is one of Germany´s and Europe´s leading forging companies, with more than 400 years of forging tradition. Since then, and until today, the company was always run by the family Diederichs. A unique wide range of products - with forged parts weighing from just 10 kg up to 32 tons - allows Dirostahl to manufacture inhouse all kinds of threedimensional geometries - varying from bars, discs, rings, blocks, shafts and shaped parts. Even now forging is still the traditional core business but over the past decades this business was extended to ring rolling, heat treatment, pre and finish machining, testing and storage facilities, of course all inhouse. We generally stock more than 25.000 tons of raw material in various sections from billets to ingots, and in more than 150 steel grades from carbon to stainless. So whatever your application, let us forge a relation. www.dirostahl.com Please see for imprint and privacy-policy : https://dirostahl.com/en/legal-notice https://dirostahl.com/en/privacy-policy
