What is a grade 43 chain?
Grade 43 has a working load limit ranging between 2,600 to 13,000 lbs. Grade 43 is also commonly labeled as High-Test Chain or G-4 chain and is comprised of carbon steel, which is known for its high tensile strength and wear resistance. This makes Grade 43 the optimal choice for applications such as: Towing.
Is G4 and G43 chain the same?
Almost all windlasses accept either HT/G43 Chain (note, HT Chain is sometimes referred to as G40, G43, or G4 chain which all work interchangeably) or BBB chain, with nearly all new windlasses requiring HT/G43 Chain.
How do you calculate chain grade?
So, to determine a chain grade, manufacturers must find the ultimate breaking strength. Then, divide that number by . 224805 to determine the ultimate breaking strength in newtons. Next, take that number and divide it by the total area of two cross-sections of a single link.
What does the grade mean on a chain?
The grade, indicated by a number, represents the strength—or mean stress value—of the chain. As the chain grade number increases: The material of the chain is typically harder and more resistant to abrasion. Strength-to-weight ratio increases. Working Load Limit (WLL) increases.
What does BBB chain mean?
Windlass Chain
BBB Anchor/Windlass Chain A short link chain of normal commercial quality. Constructed from low carbon steel. It has a uniform pitch short link and works well with gypsies. It used to be the standard for windlasses but it has largely been replaced by G4 Chain.
What is a G4 chain?
5/16 G4 has a working strength of 3,900 pounds; and a breaking strength of 11,700 pounds. 3/8 G4 has a working strength of 5,400 pounds; and a breaking strength of 16,200 pounds. 1/2 G4 weighs 2.5 pounds per foot. A standard recommended length for an all chain rode on a cruising yacht is 300 feet.

What is the working load of a chain?
Working load describes the amount of linear pull exerted on a chain by a drive while tensile strength is the amount of force required for that chain to fail. While these measurements can be related, the two terms are not interchangeable.
What can you do with a grade 43 chain?
General purpose economical chain. Used in a variety of industries and jobs including light construction, agricultural applications, and the marine industry. Grade 43 Typically used for container securement, logging, farming, towing, marine applications, and as general purpose utility chain.
Which is stronger G4 or G43 high test chain?
Product Overview More strength with lower weight makes G43 High Test chain popular for boats with electric windlasses. An excellent choice for ground tackle, Grade 43 chain is about 35% stronger than conventional BBB chain, which allows you to save weight without sacrificing anchoring security.
