THIELE Super Crown (TSC) TWN 0100
THIELE developed the TSC series of Round Link Chains with wear-resistant crowns (THIELE Super Crown)
in order to reduce link wear on plough chains and increase chain operating life.
As frictional heat in the fast running plough chains (which travel at over 3.0 m/s) leads to hardening of the
legs and to dangerous crack formation the material strength of the legs is deliberately reduced by secon-
dary heat treatment – thereby increasing the crack arrest capacity.
THIELE TSC chains are widely used on chain scraper conveyors because of the increased hardness of
their joints. This extra hardness rating inevitably means that the chains are more susceptible to stress
corrosion cracking and so TSC Chains are not recommended for corrosive environments – especially when
ftted to face conveyors.
the above values apply to chains in ‘natural black’ condition (NSW)
Strength:
Crown 378 – 413 HB10;
Leg 342 – 371 HB10
