The differences between Grade 80 and Grade 100 link chains mainly revolve around their composition, capacity, and applications:

◎ Material and Composition: Both Grade 80 and Grade 100 chains are made from high-quality alloy steel, which gives them superior strength and durability compared to lower grades like Grade 30, 43, or 70. However, Grade 100 chains often undergo additional heat treatment processes to enhance their strength and toughness.

◎ Strength and Load Capacity: Grade 100 chains have approximately a 25% higher capacity rating compared to Grade 80 chains of the same size. This means that Grade 100 chains can handle heavier loads without increasing the chain's size or weight.

◎ Applications: Both grades are suitable for overhead lifting and towing. However, due to their higher strength, Grade 100 chains are preferred in more demanding lifting applications where  safety and load capacity are critical. Grade 80 chains are also used in these applications but might be chosen when cost is a factor since they are more cost-effective than Grade 100 chains.

◎ Ergonomics: The higher strength of Grade 100 chains allows for the use of a smaller, lighter chain to lift the same load as a larger Grade 80 chain, providing ergonomic advantages and easier handling.

It's essential to consult with SHINING to determine the most suitable chain grade for specific applications based on factors like working load limits, safety requirements, and environmental conditions.
