Temperature Ratings for Chain Slings

Temperature Ratings for Chain Slings

Although extremely strong, chain tends to falter when exposed to temperature extremes. The acceptable temperature range will vary depending on the grade of the chain and will also vary in reduction of Working Load Limit (WLL).

Temperature Ratings by Chain Grade

See the chart below from the American Society of Mechanical Engineers (ASME) regarding standard B30.9-2014 and reduction in WLLs. Both temporary (while heated) and permanent (after cooled) temperatures are included. Keep in mind that the effects are cumulative over time.

This means that each time the sling heats to an excessive temperature, its WLL continues to reduce. These effects are cumulative, so each time that same chain sling is heated to the excessive temperature, its working load limit will be reduced by an additional percentage.

new chart Please note that the Occupational Safety and Health Administration (OSHA) requires all slings exposed to temperatures over 1000º F to be removed from service. When slings are exposed to extreme temperatures, contact the sling manufacturer for instruction.
