Grade 80 Binder Chain (USA)

All of our Laclede Grade 80 Chain is Made in the USA. To help identify the grade and manufacturer all of our Grade 80 Chain is embossed with”L8”. The L is the chain manufacturer Laclede. The 8 identifies this as a Grade 80 Chain. Our Grade 80 binder chain is typically finished with our black armour coating. This is a tough durable painted finish. You will also find a trace code embossed on the chain. This trace code provides Information about the manufacturing history of the chain as well as the origin of the steel. The code is a combination of letters and/or numbers located on Grade 100, Grade 80, and Grade 70 chain. These grades are all heat treated. (A process that involves heating chain to extreme temperatures to harden the material and improve the metallurgical and tensile properties of the chain).

Laclede Grade 80 chain is 100% American made produced from the highest quality domestic alloy steel. The chain is tested throughout the manufacturing process. All of our Grade 80 chain is Proof Tested to twice the working load limit. The minimum break strength is four times the working load limit. Our USA Made Grade 80 Alloy Chain meets or exceeds all existing OSHA, Government, NACM and ASTM specification requirements.

All of our Grade 80 Chain is 100 percent Proof Tested. Certs available free of charge.

Working Load Limit (WLL): (rated capacity) Is the maximum working load that should be applied In direct tension to an undamaged straight length of chain.

Proof Test: (manufacturing test force) Is a term designating the minimum tensile force which has been applied to a chain under a constantly increasing force In direct tension during the manufacturing process. These loads are manufacturing integrity tests and shall not be used as criteria for service or design purpose.

Minimum Breaking Force: The minimum force at which the chain during manufacture has been found by testing to break when a constantly increasing force is applied in direct tension. Breaking force values are not guarantees that all chain segments will endure these loads. This test is a manufacturer's attribute acceptance test and SHALL NOT be used as criteria for service and design purpose.
