High Strength: Minimum breaking strength of 800 MPa, with a load-bearing capacity far exceeding that of ordinary chains.
High Toughness: Heat-treated, it exhibits excellent toughness under impact loads, making it less prone to brittle fracture.
Abrasion and Corrosion Resistance: Surface treatments (such as galvanizing, blackening, and painting) enhance its abrasion resistance and provide some corrosion resistance.
Clear Marking: Each link is typically embossed with "G80" and the manufacturer's logo, ensuring traceability.
Safety Factor: According to standards, G80 chains are typically designed with a safety factor of 4:1 (working limit load is 1/4 of the minimum breaking strength) for lifting applications. For example, a G80 chain with a breaking force of 10 tons has a maximum safe working load of approximately 2.5 tons.
