STRAIGHT LINK (G)

Marking of a round-steel chain with straight links (G), diameter d=4 mm and pitch t=19 mm : CHAIN G 4×19 DIN 5685

TWISTED LINK (X)

-With the chains form X the measures t and b become slightly smaller by twisting which makes the weight of twist link chains by about %6 higher.
-The transformation limit corresponds to the hardness 80 N/mm2. If it is transgressed one must expect permanent transformation contraction narrowing of chain links.
-The stated strain loads represent only calculated values.
