Lifting Chains
GRADE T ( 80 ) SHORT LINK CHAIN AS2321
A short link chain made from high-quality alloy steel, quenched and tempered, conforming to the latest revision of Australian Standard AS2321. Designed for lifting applications with a 4:1 design factor, it carries a working load limit stamped on each link. The chain features a black electrophoresis finish and is proof tested during production. Available in nominal sizes from 4mm to 32mm, it is suitable for industrial lifting, rigging, and load securing.

Key Benefits
What Grade T Gives You
- Conforms to AS2321 standard with a 4:1 design factor ensuring safety under rated load
- Quenched and tempered alloy steel provides high tensile strength and impact resistance
- Proof tested during production to verify load capacity and structural integrity
- Black electrophoresis finish resists corrosion and provides a durable surface in harsh environments
- Short link design improves flexibility and reduces wear when bending around sheaves and drums
- Working load limit stamped on each link for traceability and field identification
- Welded construction ensures consistent link strength and uniform load distribution
Application Scenarios
Where Grade T Is Used
- Industrial lifting operations in manufacturing plants where chain must handle repeated dynamic loads
- Marine and offshore rigging where exposure to saltwater demands corrosion-resistant finishes
- Construction site hoisting of steel beams and structural components with consistent load transfer
- Port and logistics handling of heavy cargo using overhead cranes and lifting slings
- Mining and energy sector applications requiring reliable lifting chains under high-stress conditions
- Temporary rigging setups where chain must be reused across multiple jobs with minimal wear
Who It Is For
Buyers This Product Is Built For
- Industrial crane operators sourcing certified lifting chains for compliance with AS2321
- Marine contractors specifying corrosion-resistant chains for deck and mooring operations
- Construction companies requiring traceable, proof-tested chains for structural lifting
- Logistics and port operators managing heavy container handling with consistent chain performance

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 |
|---|---|
| Standard link chain | Short link chain has better flexibility and reduced wear when bending around sheaves, but may have slightly higher cost and less availability in large sizes |
| Grade V chain AS2321 | Grade T (80) offers higher tensile strength and breaking load than Grade V, but both conform to AS2321 and share similar safety factors |
| Galvanized chain | Electrophoresis finish provides better corrosion resistance in marine environments than standard galvanizing, but may not last as long under continuous salt spray exposure |
Use Guide
How To Use And Inspect Grade T
- Always verify the stamped working load limit matches the calculated load before use
- Inspect each link before use for deformation, cracks, or wear on the welds
- Do not exceed the working load limit under any circumstances
- Ensure the chain runs smoothly over sheaves and drums to avoid localized stress
- Avoid side loading or twisting the chain during operation
- Retire the chain if the working load limit marking is illegible or if any link shows permanent deformation
