Inox chains from the cromox® range of products are especially resistant against chemical corrosion and physical influences. Therefore, they are particularly suitable to be used as means of conveyance or application in unfavourable surroundings. Their great advantage is their extraordinary long service life and their broad area of application: industry, water supply, sewage disposal, and during application in contact with seawater.
The correct choice will dictate chain life and give you peace of mind when anchoring in adverse conditions.
cromox® stainless steel chains have a breaking force that is twice as high as regular galvanized steel chains. An added benefit is that the chains smooth surface helps prevent the formation of clusters inside the chain locker.
Stainless steels are generally regarded as seawater resistant with a PRE-value of at least 33. The cromox® Duplex material 1.4462 (AISI 318LN) has a PRE-value of 35 and is therefore seawater resistant up to 94 °F.
For anchor chains made of 1.4404 (AISI 316L), no warranty applies for use in salt water.
Ketten Wälder GmbH offers a 3 year warranty period against corrosion for its cromox® Duplex 1.4462 (AISI 318LN) chains with the electropolished finish and 2 years of warranty for cromox® Duplex chains with the bright polished finish. This warranty period comes into effect from the date of purchase.
