EPT chains, both standard and non-standard, are made of: ○ High quality steels: dimensions and adapted chemical composition for the different chain parts ○ The most efficient manufacturing processes: • Special technique for the production of bushes improving the chain wear resistance ( EPT know-how) • Plates produced by multi-stage processing tools ensuring a regular pitch ( EPT technology) ○ Adequate mechanical and heat treatments of chain parts: • Shot peening • Surface finishing • Case hardening, carbonitriding, quenching, tempering … • EPT®treatment • Freezing treatment • Corrosion protection coatings (GEOMET, zinc, nickel plating, …)
