The astm states that alloy chain shall be able to elongate a minimum of 20 before fracture.
Grade 100 chain breaking strength.
Newer and stronger still is grade 120 chain.
That number is the chain grade.
Grade 100 chain is a premium quality high strength alloy steel.
Grade 80 and grade 100 chains must include identification directly on the chain links.
The grade number used by manufacturers is an indicator toward the ultimate break strength of chain.
Grade 100 chain is 25 stronger than grade 80 chain allowing for easier handling and increased efficiency due to its higher alloy content grade 100 chain is also more rugged and resistant to fatigue.
So to determine a chain grade manufacturers must find the ultimate breaking strength.
Currently alloy chain of grade 80 or grade 100 should be used for overhead lifting.
Grade refers to the tensile strength of the metal.
Grade 100 chains are also referred to as grade 10 system 10 spectrum 10.
With galvanized chain it basically boils down to how much carbon is in the steel.
Peerless chain manufactures grade 100 alloy chain used in overhead lifting.
This allows you to reduce the size of the chain depending on the working load needed.
Any lower grade chain should not be used.
The higher the grade the greater the break strength.
Peerless grade 100 chain for sale.
Considered premium quality chain it offers about a 25 higher work load limit over grade 80 chain.
The term breaking strength is the industry standard for the amount of force that a component may be subjected to and still maintain the appropriate margin of safety.
Grade 100 chain specs have tensile strength 2x ordinary steel greatest strength to weight ratio meet existing osha nacm astm guidelines.
The number after each letter is n mm 2.
Chain slings can be shortened by twisting or by using bolts.
A newer product in the market grade 120 chain is up to 50 stronger than grade 80 chain and 20 stronger than grade 100 chain.
This number is what we see today g30 g43 g70 g80 g100 and the common chain grades.

It is safe for overhead lifting.
One of the safety measures implemented was to place chain in grades based on the ultimate breaking strength of that chain.
Then divide that number by 224805 to determine ultimate breaking strength in newtons.
Grade 100 chain has a 20 percent increase in working load limit as compared to a similar size chain in grade 80.
Grade 100 chains are embossed with a 10 or 100.
Chain grades for overhead lifting g80 g100 or g120.
