NiKrom™ - Nickel-chrome-plated bars and tubes

NiKrom is the collective brand name for Ovako's programme of nickel-chrome plated bars and tubes. On the North American market, these products are sold under the brand name Socatri.

In the NiKrom process, steel bars or tubes are first coated with a layer of corrosion-resistant nickel followed by an outer layer of hard chrome.

The duplex coating of NiKrom products combines the anti-corrosion characteristics of nickel with the favourable properties of chrome:

  • hard
  • smooth surface
  • low friction 

The result is a piston rod material exhibiting outstanding corrosion resistance and which constitutes the optimum choice for hydraulic applications in aggressive environments or applications where hydraulic function must be guaranteed long-term usage or long periods of storage. 

NiKrom can also be used to good effect in instances where piston rods must remain extended for long periods of time even if the environment is only mildly aggressive.
