• Surface: Corrud-DS-black. This coating is 20 times more red rust resistant than zinc plating.
• Chains stamped with VIP are manufactured with tighter tolerances in the inner width (size B).
• The BG (Berufsgenossenschaft : German testing authority) awarded RUD to stamp their VIP chain strands with the following:
• H1 indicates manufacturer`s number. 1=RUD.
• 8S means special quality, higher than quality grade 8 Quality Verification: At regular intervals chains are stamped with a serial and batch number.
• This identification guarantees a continuous record of the manufacturing and proof data, for a period of 10 years.
• Geometric construction and tolerances of the VIP-chains are adapted to a higher quality class. · Material: CrNiMo-special steel.
• Special heat treatment, high toughness, min. ultimate elongation for natural black 25%, Surface treated min 20%.
• Less sensitive to notching and hydrogen embrittlement than quality grade 8.
• The bending test acc. to standard specifications of DIN EN 818-2-8, bending min F=0.8xd is by far exceeded.
• WLL : manufacturing proof load : breaking force =1 : 2,5 : 4
• Owing to a special heat treatment developed by RUD, high dynamic RUD VIP-chains are more insensitive to external mechanical wear friction and to damages.
• Therefore a longer lifetime of VIP-chain is guaranteed.
