SEDIS 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 (SEDIS know-how)
• Plates produced by multi-stage processing tools ensuring a regular pitch (SEDIS technology)
○ Adequate mechanical and heat treatments of chain parts:
• Shot peening
• Surface finishing
• Case hardening, carbonitriding, quenching, tempering …
• DELTA®treatment
• Freezing treatment
• Corrosion protection coatings (GEOMET, zinc, nickel plating, …)
