New N.E.P. roller chain from Tsubaki employs an innovative metal coating process that allows a carbon steel chain to be used in wet conditions without corroding. The multi-layer metal coating process is modified for different components of the chain balancing corrosion protection with wear resistance to outperform alternative solutions many times over. An additional stand-out feature of N.E.P. chain is that its manufacturing process and component materials comply with new RoHS guidelines on restricting the use of hazardous substances such as Chromium, materials that have until now been an essential component of all high-strength corrosion resistant chain.

NEP chain will be available in Australia soon!

Tsubaki has developed two new surface treatments and applied on one chain.

The combination makes for stunning results; in a salt water immersion test Tsubaki N.E.P. chain survived over 300 hours immersion without any sign of corrosion at all, this is compared to a standard carbon steel chain that would corrode to the point of being useless within just 24 hours. Samples that have been tested up 1400 hours have shown no surface discolouration in what is one of the most destructive corrosion resistance test environments for ferrous engineering steels. (To put this achievement in context, check how much corrosion your car brake disks show after being left a couple of days with rain water on them).

In the field it is more common for the chain to be exposed to far lower concentrations of potentially corrosive water based solutions, N.E.P. chain is engineered to have extremely long service life in this environment, while maintaining all the strength of standard Tsubaki carbon steel chain. An added bonus is that N.E.P. chain is a far less expensive alternative to oversize stainless steel chains in most situations.
