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.

What are the advantages of an electropolished stainless steel chain?
Electrolytic polishing is an electrochemical process that refines surface quality.

In the electrochemical process, the total surface area is reduced through the elimination of surface roughness by means of a specially developed process. This results in superb corrosion resistance, excellent cleanability and an enhanced Chrome Dioxide layer thickness. The brilliant appearance of a mirror like surface is an additional bonus.
Which material should my anchor chain be made of?

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.

How long is the warranty for chain and components?

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.

Slings assembled from components versus welded chain slings ...
When purchasing chain slings from cromox US, you can choose between slings assembled from components or slings that are fully welded assemblies from the factory. Components give shorter lead times, but this is offset by a slightly higher initial cost. Welded assemblies are a cost effective option and allow easier inspection after prolonged use in aggressive media. However, welded assemblies will require a longer lead time prior to delivery.
Are the materials and components certified?
All our lifting, lashing and load suspension products are individually tested and certified by the factory Quality Control team.
Do I receive a certificate when purchasing cromox US products?

Yes. A certificate is issued for every manufactured and tested cromox® product in grade 60.
