Round Steel Chains

THD Round Steel Chain (THIELE Heavy Duty)

THIELE round-link chains can be used on both face conveyors and stage loaders and are also suitable as traction elements for coal ploughs. To ensure that its products can meet the tough demands of today’s mining industry THIELE has developed its own chain steels based on many years of manufacturing knowhow.
Each production stage is accompanied by careful and thorough quality control tests. THIELE chains are recognised the world over for their performance and durability.
This is why THD round-link steel chains are hardened and tempered to a strength of 345 – 375 HB10 (which applies uniformly over the entire link). For chains intended for face conveyors this strength level represents the optimum in terms of impact resistance (notch impact strength) and wear resistance (hardness).
