Grade 80 chain is a heat-treated alloy steel designed for high strength for overhead lifting and tie down applications. It is the most economical of the three chain grade types that are suitable for overhead lifting (grade 80, grade 100, grade 120). Please note that while grade 80 chain is approved for overhead lifting applications, our tie down chain assemblies are not designed for overhead lifting due to the supplied hook.

Alloy Chain is rugged, versatile, high strength, low weight chain manufactured from a special analysis alloy steel. Alloy has a comparatively high carbon content as well as containing various other alloying elements. The chain is quenched and tempered before the proof testing. The ultimate tensile strength of alloy chain is over twice that of ordinary steel chain. The chain is marked to identify grade and manufacturer. These are the only chains recommended for use in over-head lifting applications. Minimum elongation at break test 20%. Tensile strength following heat treatment meets or exceeds all existing OHSA, government, NACM and ASTM specification requirements. Regularly supplied in Black Protective Finish. Also available in Silver Shield, a cold zinc process equal in protection to hot dip galvanizing.
