Company
The company behind TripleHard® trivalent hard chrome.
Savroc Ltd (Savroc Oy), founded in 2012 in Kuopio, Finland, owns and licenses TripleHard® and holds 60+ patents. Company facts, leadership and the evidence behind TripleHard® are on this page.
We take manufacturers from the simulation of their parts to stable production in their own plants, and the licence keeps us in the project for the long term.
Vision
Where we are going.
A world where cost-effective, high-capacity TripleHard® production makes Cr(VI) hard chrome unnecessary.
Method
From proving the chemistry to scaling production.
Savroc was founded in Kuopio in 2012. We proved that hard chrome can be made with nickel and trivalent chromium instead of carcinogenic hexavalent chromium. Since then, our work has moved to the next question: how do we make that coating cost-effective and repeatable at high production capacity? We build, test, measure and improve. More than fifty versions of the process were built and run before it held. That work became the industrial-scale continuous TripleHard® line now running in Kuopio, where high-capacity continuous production is the next step.
- 01 – Proven
Make hard chrome without Cr(VI).
Nickel and trivalent chromium replace carcinogenic hexavalent chromium.
- 02 – Now
Lock cost and repeatability.
Build, test, measure and improve the process and its operating window.
- 03 – Next
Scale production.
Prove high-capacity continuous production on the reference line.
The continuous TripleHard® line in Kuopio is running, and Version 1 is complete. Continuous 24/7 production is the next step, and then we take TripleHard® into mass production on the first continuous customer line, starting in 2027.
Savroc leads every customer project. Continuous lines for hydraulic rods are built by qualified equipment partners to Savroc's process design. Industrial partners
Timeline
From a laboratory in Kuopio to a continuous TripleHard® line.
Savroc Ltd founded in Kuopio, Finland.
Selected by Nordic Cleantech Open among the 25 most promising Nordic cleantech companies.
TripleHard® proven in niche applications, but not yet at a competitive cost per part.
The breakthrough: in-house chemistry and full hardness without heat treatment.
TripleHard® rods enter mining field service: the start of the mining field cases in Canada, Australia and Poland.
The continuous process is developed on a self-built, 3D-printed pilot line. More than 50 versions tested.
The industrial-scale line arrives in Kuopio.
Installation completed on 8–9 August. First coatings produced.
Version 1 of the line complete: the first-round run parameters are locked, and optimisation continues.
Plan: mass production on the first continuous customer line, built by a qualified equipment partner, with the process commissioned by Savroc.
Licensed TripleHard® production in the world's major industrial markets.

Evidence
(Specified = an engineering or product specification · Achieved = completed and evidenced · Current = true today · Planned = a target or plan, not yet achieved)
| Industrial use | hydraulic cylinder rods, in industrial production in smaller volumes, under a Savroc licence, on a converted open-tank line at a licensed coater, with coated rods supplied to Hydroline | Current |
|---|---|---|
| OEM validation | coating validated by a major global OEM for that OEM's application; the OEM is not named | Achieved |
| Reference line | industrial-scale continuous TripleHard® line running in Kuopio, Version 1 complete (first-round run parameters locked, optimisation continues), open for visits | Current |
| Engine valves | tested on valve stems; offered for licensed production on a converted existing line, coated in open tanks or in a coating cell of their own, not on the continuous line; volume production is possible, but it has not started yet | Current |
| Shock absorber rods | coating cell designed by Savroc; coated on a converted existing line or in that cell, not on the continuous line; volume production is possible, but it has not started yet | Current |
| Mining field case | no rust at 34 months; 34 months is the latest documented inspection, and the coating remained in service after that | Achieved |
| Field cases | mining on three continents (Canada, Australia and Poland), 2020–2026; a high-pressure water pump in high-salinity water in Canada | Achieved |
| Neutral salt spray | rating 10 at 1000 h, ISO 9227, depending on the nickel underlayer | Achieved |
| Seal surfaces | lower seal leakage than the Cr(VI) reference in a 250,000-cycle test by a global OEM | Achieved |
| Heat | hardness is maintained after heat cycling to 500 °C | Achieved |
| Next step | high-capacity continuous 24/7 production, not yet run; proving it for hydraulic cylinder rods is the job of the reference line in Kuopio | Planned |
| Mass production on the first continuous customer line | 2027 | Planned |
Roadmap
| Now | TripleHard® replaces nickel + Cr(VI) coatings on hydraulic cylinder rods and engine valves, both at once; this is where the technology is proven and where customers are ready now, and from here the same technology is scaled to more applications and plants | Current |
|---|---|---|
| From 2028 | Replacing Cr(VI) hard chrome across applications, as fast as lines can be built and converted | Planned |
| Shock absorber rods | third application, on a converted existing line or in a coating cell designed by Savroc | Current |
| Scale | as more lines are built, TripleHard® becomes more accessible and more cost-effective for more applications | Planned |
