Grade 80 Chain vs Other Grades
Grade 70 vs Grade 80 Chain
You often see Grade 70 and Grade 80 chains used in different environments. Grade 70 chain works well for transport and tie-down tasks. It is not rated for overhead lifting. Grade 80 chain, on the other hand, is designed for lifting and rigging. You can trust it for critical applications where safety is a priority.
Grade 80 chain offers higher strength than Grade 70 chain of the same size. For example, a 3/8″ Grade 70 chain has a working load limit (WLL) of 6,600 lbs, while a 3/8″ Grade 80 chain handles 7,100 lbs. As the chain size increases, the difference in capacity becomes even more significant.
Grade 80 chain can reach up to 47,700 lbs in larger sizes, making it suitable for heavy-duty lifting.
Chain Size (inch) | Grade 70 WLL (lbs) | Grade 80 WLL (lbs) |
|---|---|---|
1/4″ | 3,150 | 3,500 |
5/16″ | 4,700 | 4,500 |
3/8″ | 6,600 | 7,100 |
7/16″ | 8,760 | 10,000 |
1/2″ | 11,300 | 12,000 |
5/8″ | 15,800 | 18,100 |
You also notice a price difference. Grade 70 chain costs less, usually $1.00–$2.50 per foot. Grade 80 chain ranges from $2.00–$4.00 per foot. You pay more for Grade 80 because it meets strict safety standards for lifting applications.
Grade 80 vs Grade 100 Chain
You may consider a Grade 100 chain for the most demanding lifting jobs. Grade 100 chain uses high-performance alloy steel and advanced heat treatment. It provides about 25% higher working load limit than the Grade 80 chain of the same diameter. This means you can use a smaller, lighter chain for the same load.
Grade 100 chain costs more, usually $3.00–$6.00 per foot. You choose Grade 100 when you need maximum strength and efficiency. Grade 80 chain remains a reliable choice for most lifting and rigging applications, balancing strength, safety, and cost.
Choosing the Right Chain for Your Needs
You must select the right chain for your specific applications. Start by understanding the differences in chain grades, including material, heat treatment, and ultimate strength. Always check the working load limit for safe lifting. Consider the nature of your lift and the environment.
For overhead lifting, Grade 80 or Grade 100 chains are essential. For transport or tie-down, Grade 70 may be enough.
You should also choose the correct size and style of chain and hooks. Proper selection is not just a recommendation—it is a safety requirement. Store and inspect your chains regularly to maintain integrity. Using the right chain for the job protects you and your team.
Tip: Never use a chain above its rated working load limit. Always match the chain grade to your lifting or securing needs.
