The new HEKO UR400 quality specifically leverages the effect of stress-induced structural transformation.
In operation, the already case-hardened material undergoes additional hardening precisely in the areas subjected to the highest loads. This creates an innovative microstructure with an optimal combination of hardness, toughness, and fatigue strength. The result is a round steel chain with maximum fracture toughness and wear resistance.
HEKO UR400 offers you:
Increased Operational Fatigue Strength – The ductile edge layer allows higher breaking strength despite the increased case-hardening depth, sustainably improving fatigue performance.
Enhanced Wear Protection – Targeted in-service hardening in the highly stressed zones of the chain links provides significantly improved wear resistance.
Extended Service Life – The optimized wear protection increases service life by up to 30% at comparable breaking stress.
Exclusively at HEKO – engineered for the highest demands.
