Grade 43 Chain

Grade 43 aka grade 40 has higher tensile strength and abrasion resistance and comes with a higher price tag.

Grade 43 chain.

It is designed for use in load binding towing logging and other applications requiring high strength chain. Grade 43 high test chain is heavy duty high strength welded steel chain. Grade 43 chain is embossed using a 43 or a g4. Alloy chain grade 80 or grade 100 should be used for overhead lifting.

The grade refers to the tensile strength of the chain. 4 thoughts on chain grades.

Grade 30 chain is a general purpose chain often used in industrial and agricultural applications. G43 chains are also referred to as high test chain grade 40 spectrum 4 or system 4. Grade 43 chain features both high tensile strength and resistance to wear needed by modern hauling and heavy duty trucking farm and construction firms. Grade 80 alloy chain is heat treated making it.

It is not rated safe for overhead lifting. Grade 43 chain is a steel chain that possess greater tensile strength than proof coil chain. Comparing grade 30 grade 43 grade 70 grade 80 grade 100 and grade 120 chain paul hepworth says. Widely used for trailer safety chain tow log chain guard chain and general purpose utility chain.

Grade 43 chain typically has a 50 higher working load limit than proof coil or grade 30 chain. The chain s working load limit will have to be of sufficient strength to support the weight of the load plus any additional forces imposed by angles and hitch type s used. Grade 43 log chains are made with grade 43 chain a higher strength carbon steel chain also known as high test chain self colored no. Astm states that alloy chain shall.

Grade 30 aka proof coil has less carbon and is good service duty chain. It can be used for load securement but is of less strength than grade 43 chain.
