 Alloy is rugged, versatile, high strength, low weight chain manufactured from a special analysis alloy steel. Alloy has 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 exceeds all existing OHSA, government, NACM and ASTM specification requirements.
