Grade 100 Alloy Steel Material

EN818-2 Grade 100 Lifting Chain is manufactured from quenched and tempered high-quality alloy steel for overhead lifting applications. The heat treatment process improves tensile strength and fatigue resistance during repeated lifting cycles. Compared with Grade 80 lifting chains, Grade 100 chains provide approximately 25% higher Working Load Limit under the same nominal diameter, allowing users to achieve higher lifting capacity without increasing chain size.

The chain is designed for use in:

  Chain sling assemblies

  Crane lifting systems

  Offshore lifting operations

  Industrial rigging

  Heavy equipment handling

  Construction lifting applications

EN818-2 Short Link Structure

Grade 100 Lifting Chain is manufactured according to EN818-2 short link chain requirements. The short link design improves load distribution and maintains stable engagement with lifting components during overhead lifting operations.

  The calibrated structure controls:

  Link pitch consistency

  Internal width tolerance

  Dimensional accuracy

Compared with long link chains, short link lifting chains provide improved load stability and reduce abnormal movement during lifting operations.

25% Higher Capacity than Grade 80

One of the main advantages of Grade 100 Lifting Chain is its increased lifting capacity. Under the same chain diameter, Grade 100 chains provide approximately 25% higher Working Load Limits than Grade 80 chains.

For lifting operations, this means:

  Higher lifting capacity without increasing chain size

  Reduced sling weight for equivalent lifting loads

  Improved handling efficiency during rigging operations

  Greater flexibility in equipment selection

This performance improvement allows many lifting assemblies to use smaller diameter chains while maintaining required Working Load Limits.

Quenched and Tempered Performance

The chain is produced through controlled quenching and tempering processes. This heat treatment improves the mechanical properties of the alloy steel and helps maintain stable performance during cyclic loading conditions.

During operation, lifting chains continuously experience:

Tensile loading

Dynamic shock loading

Repeated fatigue cycles

Abrasive contact between links

Heat-treated alloy steel improves resistance to wear and impact compared with untreated carbon steel chains used in general industrial applications.

Surface Treatment Options

Grade 100 Lifting Chain is available with multiple surface finishes according to operating environment requirements.

Available surface treatments include:

  Self color

  Polishing

  Blackened

  Painted

  Plastic coating

  Electro galvanized

  Hot-dip galvanized

Hot-dip galvanized coatings improve corrosion resistance during offshore, marine, and outdoor applications. Electro galvanized finishes provide a uniform zinc coating for moderate corrosion environments. Blackened finishes are commonly used for indoor lifting systems where lubricant retention is important.

Product Identification and Traceability

Each Grade 100 chain is marked for identification and traceability purposes.

Typical markings include:

  Grade 100 identification

  Manufacturer identification

  Production batch information

Traceability markings support inspection procedures, maintenance records, and quality management requirements throughout the service life of the chain.

Application Compatibility

EN818-2 Grade 100 Lifting Chain is suitable for use with Grade 100 lifting components including:

Master links

  Connecting links

  Shortening clutches

  Sling hooks

  Multi-leg chain slings

All lifting components within the assembly should match the Grade 100 system to ensure the Working Load Limit of the complete sling assembly is maintained according to EN818 standards.

Safety Factor

Grade 100 Lifting Chain is designed with a minimum safety factor of 4:1 for overhead lifting applications. Manufacturing, testing, and inspection procedures verify compliance with lifting chain requirements before shipment.

Each production batch commonly undergoes:

  Proof load testing

  Breaking force testing

  Hardness inspection

  Weld inspection

  Dimensional verification

These inspections help ensure conformity with EN818-2 requirements for industrial lifting operations.

Manufacturing Standards

Manufactured according to EN818-2 Grade 100 short link lifting chain standards using quenched and tempered alloy steel for overhead lifting applications.

Testing Standards

Each batch passes proof load testing, breaking force testing, weld inspection, hardness testing, and dimensional verification according to EN818-2 requirements.

Application Standards
