The strength of steel chains

Steel chain grades

The different grades of steel chain offer a wide range of options to suit different applications and environments. Identified by an alphanumeric designation, such as G30, G70 and G80, each grade represents the strength limit of the chain, expressed in newtons per square millimetre. For example, grade 80 (G80) indicates that the chain can withstand a maximum load of 800 Newtons per Square Millimetre.

The choice of chain grade depends on the type of application and specific strength requirements. For instance, UNIQ Grade 80 chains are ideal for overhead lifting applications due to their high strength and load capacity.

In terms of safety regulations, chains must have a minimum elongation of 20%, and alloy components are used in their manufacture to ensure that alloy chains consistently meet this requirement. 

This ensures that the chains maintain their structural integrity and strength even under heavy loads and demanding conditions, providing increased safety and durability in a variety of industrial and lifting applications.
