Description

Rich of more than 60 years development in industrial conditions, Salt bath nitrocarburizing (SBN) has been able to adapt itself to match standards in so different fields (Aeronautics, Energy, Automotive, Construction Equipment, Military…).

Thus, SBN is nowadays an essential surface treatment solution, globally established and recognized with more than 500.000 tons of parts yearly treated with SBN process.

The HEF's SBN leads to a unique combination of surfaces performances, like high corrosion resistance, friction properties, wear protection which allow increasing drastically lifetime of treated components. The safe liquid medium, in situ regenerated, used as nitrogen and carbon source permits homogeneous treatment of complex parts' shapes. It also represents the highest robustness, stability and productivity compared to others thermochemical treatments (gas and plasma).

Based on its worldwide presence, its continuous improvement and high industrial maturity, HEF's SBN is the easy-operate technology ready for future with its “ road to CLIN 4.0” program. Indeed, SBN is released as replacement of others surfaces treatments solutions such as hexavalent chromium plating. That’s why HEF's SBN is proven to be not only an alternative on both technical aspects and price competitiveness but also a real solution answering environmental challenges.

Environmental constraints are the highest priority in the continuous development of this treatment worldwide. This process has already replaced and will keep on substituting pollutant technologies. Aiming to reach and to overtake current legal local regulations and their future releases, HEF develops its SBN activities in compliance with the most severe environmental standards in the world. The recent HEF’s development of an industrial recycling of consumables leads to a liquid effluent free operation. Finally, this nitrocarburizing process does not contain any COV (no use of organic solvents), any NOX (no need of burners used for gas detoxification), or other hazardous compounds.
