What is the Astm Standard?
ASTM standards set clear, global benchmarks for materials and products. When you use ASTM-certified chains, you ensure every chain meets mechanical, durability, and safety requirements. Standards such as ASTM A413 for Grade 30, ASTM A391 for Grade 80, and ASTM A906 for Grade 100 define alloy composition, heat treatment, dimensions, and minimum working loads. Choosing ASTM-certified chains reduces operational risk and delivers superior performance compared to non-certified alternatives.
What Are the Key Astm Chain Classifications?
ASTM chains classify by grade and application:
- Grade 30 Proof Coil Chains: Light-duty, general-purpose, suitable for agriculture.
- Grade 43 High Test Chains: Stronger chains for towing, load binding, and construction.
- Grade 70 Transport Chains: Heat-treated chains for cargo securement and trucking.
- Grade 80 Alloy Chains: Alloy chains for overhead lifting and industrial rigging.
- Grade 100 Alloy Chains: High-performance chains for heavy-duty lifting and demanding industrial operations.
Each grade has defined working loads, elongation limits, and recommended applications. Our chains provide certified compliance and batch traceability, ensuring safety and reliability.

How Should I Maintain Astm Chains?
Regular maintenance of ASTM chains protects workers, extends chain life, and ensures safe, reliable performance across lifting, towing, rigging, and cargo operations. Follow these steps for all chain grades:
1. Inspect Chains Regularly
- Check for wear, elongation, cracks, corrosion, or deformation.
- Verify hooks, shackles, and connectors for damage or compatibility issues.
- Record inspection results for traceability and compliance with safety standards.
2. Clean Chains After Use
- Remove dirt, dust, saltwater, and chemical residues.

- Ensure the chain is fully dry before storage to prevent rust.
3. Lubricate Moving Parts
- Apply industrial-grade oil to reduce friction and wear.
- Focus on pivot points and links that experience constant movement.
- Avoid excessive lubrication that attracts dust or debris.
4. Store Chains Properly
- Keep chains off the ground on racks or hooks.
- Store in a dry, ventilated area to prevent moisture accumulation.
- Avoid direct contact with corrosive chemicals or extreme heat sources.
5. Replace Worn or Damaged Chains
- Remove any chain that exceeds elongation or wear limits.
- Replace links showing cracks, deformation, or severe corrosion.
- Always follow grade-specific working load limits when replacing chains.
6. Track Usage and Load History
- Maintain records of hours of use and applied loads for each chain.
