Compare
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 V chain is stronger than Grade 80 and allows lighter chain use in some lifts, but Grade 80 may be more cost-effective for lower-duty applications |
| Standard link chain | Short link design improves load distribution and reduces wear at contact points, but standard links may be easier to inspect in some field conditions |
| Galvanized chain | Electrophoresis finish offers better corrosion resistance in industrial environments than galvanizing, but galvanized chains may be preferred in wet or chemical exposure |
| Non-proof tested chain | Proof load testing ensures each batch meets minimum breaking force, reducing risk of failure compared to chains without testing |
Use Guide
How To Use And Inspect Grade V Short Link Chain AS2321
- Always verify the stamped working load limit matches the calculated load before use
- Inspect the chain for deformation, wear, or damage before each lift, especially at the welds and links
- Do not exceed the working load limit under any circumstances, even for short durations
- Use only with compatible fittings such as shackles and hooks that meet the same design factor
- Keep the chain clean and dry; clean with mild detergent if exposed to salt or chemicals
- Retire the chain if the marking is illegible, the link shows deformation, or the surface finish is compromised
- Store in a dry, covered area to prevent corrosion and maintain surface integrity

Answers
Grade V Short Link Chain AS2321 FAQ
What does Grade V mean on this chain?
Grade V refers to the strength classification of the alloy steel used. It is part of the AS2321 standard and indicates a 4:1 design factor with a minimum breaking load four times the working load limit.
Is this chain proof load tested?
Yes. Each production batch is proof load tested to validate the working load limit and minimum breaking force. Test results are recorded and available upon request.
What surface finish is applied?
The chain is finished in either blue or black electrophoresis. Both provide corrosion resistance and are suitable for industrial and outdoor use.
Can I get a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order on request. It confirms the material grade and mechanical properties.
What is the design factor?
The design factor is 4:1, as required by the AS2321 standard. This means the minimum breaking load is four times the stated working load limit.
Can I order custom sizes or markings?
Yes. Custom tonnage stamping, private label marking, and custom sizes built to a drawing are available. Packing can also be configured to your warehouse or retail needs.
How is the chain packed for export?
Standard packing is in drums on steel pallets. We can also configure carton and pallet patterns to suit your warehouse or retail pack. Goods can be held in our Qingdao warehouse free for two months.
