What is the minimum grade of chain required for chain slings?

The minimum grade of chain required for chain slings is Grade 80. This is because Grade 80 chain is specifically designed for lifting and rigging applications, offering higher strength and durability compared to lower grades of chain like Grade 30 or Grade 50. Grade 80 chains have a minimum breaking strength that is significantly higher, making them suitable for industrial lifting operations where safety is a priority.

Additionally, Grade 80 chains are often heat-treated, contributing to their ability to withstand heavier loads and providing better resistance to wear and fatigue. This is critical in ensuring that the chain sling can safely handle the dynamic load conditions encountered in lifting tasks. Higher grades, such as Grade 100, while stronger, are not typically mandated as the minimum; Grade 80 fulfills the necessary strength requirements for most standard lifting applications.
