Technical data

We focus on pressure-nitrided austenic steels or HNS qualities. HNS stands for "High Nitrogen Steels".  Our PESR process makes it possible to produce these unique steels, which have meanwhile become well established on the stainless steel market. The outstanding properties of these steels include high corrosion resistance, very high strength, very good toughness and a higher hardness. These properties make the steels produced by Energietechnik Essen GmbH ideal structural materials – with a wide range of applications. It is, of course also possible to produce alloys in strict accordance with customer specifications. In our ESU and PESR plants we are able to produce ingots weighing between 2 t and 26 t. 

Solutions for the individual requirements of our customers: 

Custom-made alloys with 

  • high corrosion resistance
  • extremely high strengths
  • extremely good toughness properties and
