Black-Magic chain

Description

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 it 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. the ultimate elongation for natural black 25%, Surface treated min 20%.
Less sensitive it to notching and hydrogen embrittlement than quality grade 8.
The bending test acc. the standard specifications of DIN EN 818-2-8, bending min F=0.8 xd is by far exceeded.
WLLS : 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 their external mechanical wear friction and to damages.
Therefore a longer lifetime of VIP-chain is guaranteed.
