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.
Grade 100 chain breaking strength.
Peerless chain manufactures grade 100 alloy chain used in overhead lifting.
Currently alloy chain of grade 80 or grade 100 should be used for overhead lifting.
This allows you to reduce the size of the chain depending on the working load needed.
The higher the grade the greater the break strength.
So to determine a chain grade manufacturers must find the ultimate breaking strength.
It is safe for overhead lifting.
Grade 100 chain has a 20 percent increase in working load limit as compared to a similar size chain in grade 80.
That number is the chain grade.
Then divide that number by 224805 to determine ultimate breaking strength in newtons.
This number is what we see today g30 g43 g70 g80 g100 and the common chain grades.
Next take that number and divide by the total area of two cross sections of a single link.
The grade number used by manufacturers is an indicator toward the ultimate break strength of chain.

Chain grades for overhead lifting g80 g100 or g120.
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.
Peerless grade 100 chain for sale.
Grade 100 chain is a premium quality high strength alloy steel.
The number after each letter is n mm 2.
Grade 100 chains are also referred to as grade 10 system 10 spectrum 10.
Grade 100 chains are embossed with a 10 or 100.
Newer and stronger still is grade 120 chain.
Grade 100 chain specs have tensile strength 2x ordinary steel greatest strength to weight ratio meet existing osha nacm astm guidelines.
Grade 30 aka proof coil has less carbon and is good.
With galvanized chain it basically boils down to how much carbon is in the steel.
One of the safety measures implemented was to place chain in grades based on the ultimate breaking strength of that chain.
Any lower grade chain should not be used.
The astm states that alloy chain shall be able to elongate a minimum of 20 before fracture.
Grade 100 chain is quickly becoming the more popular choice for construction manufacturing and rigging companies grade 100 chains is approved for overhead lifting applications.
Grade refers to the tensile strength of the metal.
Grade 80 and grade 100 chains must include identification directly on the chain links.
