Note: Grade 80 alloy chain is approved by OSHA for overhead lifting.
Like our grade 100 chain, this Advantage Sales GRADE 80 Lifting Chain is low weight, but high strength alloy steel with comparatively high carbon content. Quenched and tempered before proof testing, the ultimate tensile strength of our alloy chain is double that of ordinary steel chain. Chain embossed with grade marking every 36″. Self colored.
Our GRADE 80 lifting chain also meets or exceeds all existing OSHA, Government, NACM, and ASTM requirements.
