GRADE 8 VS GRADE 10: PROS AND CONS

What to consider when choosing between Grade 8 and 10?

* Generally a Grade 10 chain of one chain size smaller than its Grade 8 counterpart is capable of lifting the     

   same load, which will result in a considerable reduction in sling weight.

**Extreme Heat Conditions

The strength of all chain slings is adversely affected by heat, and care must be exercised when using chain slings at elevated temperatures.

 

Where the temperatures are likely to be higher than 200    , it will be necessary to de-rate the specified WLL as per the below WLL reduction guidelines table.

 

Note: Grade 10 chain is not be used in applications > 200

HEAT TREATMENT
Max-Alloy® Grade 8 chains and fittings do not require periodic heat treatment and must never be reheated other than by McKinnon Chain.


SURFACE COATING
Max-Alloy® Grade 8 products should not be galvanized or subjected to other plating processes without the approval of McKinnon Chain.


Please contact our Max-Alloy® distributor for detailed recommendations. We are mass chain suppliers.
