Corrosion-resistant chains
Four main factors have an impact on chain corrosion: the medium or environment in which the chain operates, the chain material, machinery or plant design, and the duration and type of application. These main parameters help to define the right chain for a given application.
Corrosion-resistant chains with alternative coatings are also available on request. For example, iwis meets special customer requirements by combining different coatings to achieve high wear resistance while guaranteeing a high level of corrosion protection for attachments.
Stainless steel chains are used mainly in food production or in applications where frequent chain cleaning is required. iwis supplies stainless steel chains made from materials that ensure they can be used in acidic or alkaline environments. Versions with bent attachments, special attachments and extended pins are also available.
CR chains are corrosion-resistant, made from hardened, highly alloyed steel grades, and have significantly higher tensile and fatigue strength than ordinary rustproof (stainless steel) chains. CR chains are used in all applications that require chains to remain flexible despite corrosive environments, or to remain rust-free for hygienic or visual reasons.
