How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Grade 43 Chain | Grade 80 offers higher strength and breaking load, suitable for heavier lifting but costs more and requires more careful handling |
| Galvanized Chain | Electrophoresis finish provides better corrosion resistance in industrial settings than standard galvanizing, with a smoother surface and longer service life |
| Non-welded Chain | Welded construction ensures consistent strength and uniformity, but may be less flexible than non-welded types in tight bends |
| Rope Slings | Chain provides superior abrasion resistance and durability under heavy loads, but is heavier and less flexible than synthetic slings |
Use Guide
How To Use And Inspect Grade 80 Alloy Chain NACM2010
- Always verify the stamped working load limit matches the calculated load before lifting
- Do not exceed the maximum working load limit under any condition
- Inspect the chain before each use for wear, deformation, or surface damage
- Ensure the black electrophoresis finish is intact; repair or replace if compromised
- Avoid side loading or twisting the chain during lifting operations
- Use with compatible fittings such as shackles and hooks that meet the same load rating
- Retire the chain if the working load limit marking is illegible or if the chain shows visible deformation
