Round link chains hardened

The greater the hardening depth of the round link chain, the higher the abrasion resistance

Depending on the application, one can choose a round link chain in a certain size, but then with a higher breaking load or an increased resistance to wear and tear. One can choose from various materials or from one of many curing methods. Of course, a combination of both can be created. The hardening depth of the wire in the hinges is important. The greater the hardening depth, the higher the abrasion resistance. However, a higher hardening depth can lead to a lower breaking load. Generally, the rule is that the hardening depth can be up to 14% of the wire diameter.
