In order to secure the longest possible service life for the chains, the steel for the chains will be hardened to make it highly wear-resistant. Thus processed, the chains have an excellent surface hardness and, at the same time, a high core tenacity and breaking strength. All this will ensure maximum fatigue strength. Our customers get chains and accessories with a compatibility that will guarantee a high operational safety and a long service life.
