Sheet1.HERCULES GRADE 80 ALLOY CHAIN SPECIFICATIONSChain sizeWeight lb/100 ft.Working load limit*Alloy Steel Chain is electrically welded al-loy steel embodying the latest manufactu-ring technology. Alloy provides a superior chain sling with high tensile strength and ex-cellent wear resistance. The minimum elon-gation at break test is 15%. The tensile strength following heat treatment exceeds all existing CSST, Government, NACM, and ASTM specification requirements.inchesmmpoundskg7/325422,1009509/327713,5001,5905/168894,5002,040The alloy chain and attachments used in fabrication HERCULES chain slings offer a design factor of a minimum of 4 to 1 when used at recommended working load limits.3/8101447,1003,2001/21323612,0005,4005/81638018,1008,2003/42055628,30012,9007/82273534,20015,50012597547,70021,6001 1/4321,52072,30032,800*WARNING: Never exceed working load limit.
