CorX Mining Chain
The alloy steel material specification for COR-X chain was developed
and patented in 1997 to overcome the effects of the most corrosive
mining conditions.
High levels of acidity, conductivity, soluble chlorates and sulphates
in the mine water will inevitably lead to the development of surface
corrosion pitting which can result in premature failure due to the
effects of corrosion fatigue or stress corrosion cracking.
Unlike chain which is surface galvanised, COR-X chain properties are
inherent in the whole link, will not wear off and last the life of the
chain.
Parsons COR-X mining chains are thus virtually immune to the effects of
corrosion pitting and have proven reliability on many of the world’s
key conveyor installations.
