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 80 Chain | Grade 100 offers 25 percent higher strength for the same nominal size, allowing lighter chain use without compromising safety |
| Galvanized Chain | Electrophoresis finish provides better uniformity and adhesion than galvanizing, especially on welded joints |
| Forged Chain | Welded link construction is more cost-effective and suitable for standard overhead lifting, though forged chain may offer higher fatigue resistance |
| Stainless Steel Chain | Grade 100 alloy chain has higher strength and load capacity than stainless steel for the same size, but stainless is better in highly corrosive chemical environments |
Use Guide
How To Use And Inspect Grade 100 Alloy Chain NACM2010
- Always verify the stamped working load limit matches the calculated load before use
- Do not exceed the working load limit under any circumstances
- Inspect the chain before each use for signs of wear, deformation, or coating damage
- Avoid side loading or twisting the chain during lifting operations
- Keep the chain clean and dry; clean with mild detergent if exposed to salt or grime
- Retire the chain if the welds show cracks, the links are stretched, or the marking is illegible

Grade 100 Alloy Chain NACM2010 FAQ
What is the difference between Grade 100 and Grade 80 chain?
Grade 100 chain is stronger than Grade 80 for the same nominal size. It allows lighter chain use in overhead lifting while still meeting the 4:1 design factor required by NACM.
Is this chain proof tested?
Yes. Every production batch is proof load tested to validate the minimum breaking force and ensure compliance with NACM2010 specifications.
What surface finish is used?
The chain is finished in blue or black electrophoresis. No galvanizing or zinc plating is used. The finish provides corrosion resistance and uniform coverage.
Can you supply a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with each order. It confirms the material composition and mechanical properties.
What is the design factor for this chain?
The design factor is 4:1, as required by NACM2010. The minimum breaking force is four times the stated working load limit.
Can you custom stamp our brand or tonnage?
Yes. Custom tonnage stamping, private label marking, and OEM branding are available on bulk orders. The finish and packing can also be configured.
How is the chain packed for export?
Standard packing is in drums on steel pallets. We can configure drum size and pallet load to suit your warehouse or shipping needs. Free storage in Qingdao for two months is available.
