How strong is Grade 100 chain?

Grade 100 chain is also comprised of alloy steel – which is heat treated for higher strength and durability. Grade 100 chain is available with working load limits between 4,300 to 35,300 lbs.

What is the difference between grade 80 and grade 100 chain?

In comparison to Grade 80, Grade 100 chain has a significantly higher strength-to-weight ratio—about 25% higher, depending on the manufacturer. Grade 100 chain also has a slightly harder surface material, which gives it some advantage when it comes to abrasion resistance.

What does the grade mean on a chain?

Chain grades are a standard method for showing the ultimate breaking strength (tensile strength) of a chain. Grades help determine what sort of applications are appropriate for a given chain. Chain grades are determined by calculating newtons per square millimeter, using the formula “N/mm2”.

What is Grade 100 chain used for?

Alloy Chain Grade 80 or Grade 100 should be used for overhead lifting.

How can I tell what grade my chain is?

What is a grade 100 chain?

Grade 100 chain is identified with “L10”, “P10” or similar grade markings forged into each link or every third link. Grade 100 chain is forged, quenched, tempered and the proof tested. A gray/black armor coating protective finish is applied to the chain during the manufacturing processes.

What is a Grade 30 chain used for?

Perfect for light construction, agriculture, or marine and household applications like swing sets or guard railers. Grade 30 chains are composed of malleable, rust-resistant carbon steel and have a working load limit between 1,300 to 6,900 lbs depending on the size of the link.

How do I identify a grade 80 chain?

To help identify the grade and manufacturer all of our Grade 80 Chain is embossed with”L10”. The L is the chain manufacturer Laclede. The 10 identifies this as a Grade 100 Chain. On sizes 3/4″, 7/8” and 1” grade 100 chain ) it will be embossed with P10 or P100. The manufacturer is Peerless Chain.

What is the difference between grade 80 and grade 100 chain slings?

A Grade 100 chain sling has approximately 25% more capacity than a Grade 80 chain sling of the same size. Grade 100 Alloy Chain Slings allow you to lift the same load with a smaller size chain and less weight than Grade 80 chai n.
