Minimum grade for alloy steel chain used for hoisting per ASME B30.9?

Explanation:
When selecting chain for overhead lifting, the grade tells you how strong and tough the chain will be under load. ASME B30.9 requires that alloy steel chain used for hoisting be at least Grade 80. This level provides the necessary tensile strength and ductility to handle the dynamic and shock loads encountered during lifting. Lower grades are used for other rigging purposes and do not meet the overhead lifting requirements. So, the minimum grade permitted for alloy chain used for hoisting is Grade 80.
