Alloy Chain Slings

Alloy Chain Slings are the most durable overhead lifting slings available. Built from heat-treated alloy steel, they offer superior resistance to abrasion, cutting, and high temperatures compared to synthetic alternatives. With proper maintenance and regular inspection, alloy chain slings can remain in service for decades.

Amick fabricates alloy chain slings in both Grade 80 and Grade 100. Grade 80 chain is manufactured to ASTM A391 specifications and is widely used across general industrial lifting. Grade 100 chain, manufactured to ASTM A973, provides approximately 25% higher working load limits than Grade 80 at the same chain diameter — delivering greater lifting capacity with less sling weight. Both grades are available in all standard configurations: Single Leg (SOS), Double Leg (DOS), Triple Leg (TOS), and Quadruple Leg (QOS).

All Amick chain sling assemblies are proof tested and built with a 4:1 design factor in accordance with ASME B30.9 and OSHA requirements. We offer both welded and mechanical assemblies with a full range of hooks — including plate, sling, foundry, grab, stirrup, and mold styles. Our chain slings are also RFID-ready for enhanced tracking and inspection management.

Every chain sling is fabricated at our Pittsburgh facility. Don't see exactly what you need? Sketch it and we'll make it.

Type

Grade 80 (ASTM A391) and Grade 100 (ASTM A973) alloy steel chain. Single Leg (SOS), Double Leg (DOS), Triple Leg (TOS), and Quadruple Leg (QOS) configurations. Welded and mechanical assemblies. Hooks: Plate, Sling, Foundry, Grab, Stirrup, Mold.

Applications

Heavy-duty overhead lifting in construction, steel erection, manufacturing, foundry, shipyard, and plant maintenance operations. Preferred for applications involving elevated temperatures, abrasive loads, or environments where synthetic slings would degrade. Also well suited for repetitive production lifting where long service life and repairability are priorities.

Exceptions

Both Grade 80 and Grade 100 alloy chain slings maintain full rated capacity up to 400°F (205°C). Above 400°F, rated loads must be reduced per the manufacturer's derating chart. Alkalies and strong acids are harmful to alloy chain material. Do not use chain slings with visible damage including stretched, bent, twisted, or cracked links. Periodic inspections are required at intervals not exceeding 12 months per ASME B30.9.
