The "total package" for strip and sheet processing

Cold rolls are used in cold forming of low-, high-alloy steels and non-ferrous metals and must meet specific requirements. For this reason, they are a special field of cold-work steels.

Various machining and special steel in perfect harmony

Deutsche Edelstahlwerke supplies cold rolls, from blanks to ready-to-use rolls, exclusively from its own production - from steel production to hot forming, heat treatment and mechanical processing. The use of special metallurgical processes such as electro-slag remelting (ESR) or vacuum-arc remelting (VAR) guarantees the quality of high surface quality, low purity and good isotropy of the material.

Special steels that have been optimized in their chemical composition to meet the special requirements and the production of the rolls.

  • 2 - 3% Cr steels: Due to their alloy state, these steels have a balanced ratio of hardness, hardening depth and toughness. These steels are used exclusively for surface-hardened rolls. For special requirements, Deutsche Edelstahlwerke also offers all variants in remelted condition.
  • 5% Cr steel: Compared to the 2 - 3% Cr steels, this steel has a higher compressive strength. It can be used through-hardened or shell-hardened condition.
  • 7 - 12% Cr steels: These steels are mainly used for through-hardened cold rolls. In special cases Deutsche Edelstahlwerke can also produce partially hardened cold rolls made from these steels.
