Although extremely strong, chain can still be negatively affected 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).
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 is heated to an excessive temperature, its WLL will be further reduced.
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.
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.

A common question we hear is what is the difference between a snatch block and other types of blocks and pulleys?
All of the items we sell in the Snatch Blocks & Wire Rope Pulleys category can be called blocks or wire rope pulleys, but snatch block refers to a particular type of block. A snatch block has a side plate sometimes called a cheek plate, that can be opened for easy insertion of cable without having to remove the load or fittings from the end of the wire. The process of inserting a line into a block is called reeving.
Snatch blocks are often used in applications to move loads over short distances, as opposed to long lifts and continuous service. They are called snatch blocks because they are often used in conjunction with a winch in a recovery application, and can improve the functionality of a winch by increasing its pull power. It also allows you to change the direction of your winch’s cable when the anchor point is offset.
With so many different styles and weight and size safety guidelines, it’s important to know what to look for when choosing a snatch block for the job. Important safety factors to keep in mind:
Check the Work Load Limit (WLL) of the snatch block as well as the wire rope. If the WLL of the wire is not compatible with the WLL of the pulley, it can be extremely dangerous should either fail.
Coordinate the size of the sheave in the snatch block to the diameter of the wire rope. If the wire rope is too large for the sheave, it can crack the block when under pressure. Generally, the wire rope-to-sheave size ratio should be 12:1 in order to hold the wire properly while under load.
Know your numbers. Because a snatch block can cut the direct pull load in half, choose a rigging pulley that has a rating of double the pull of the winch you’ll be using with it.
Choosing the right block and all the equipment to go along with it can be confusing. If you have any questions about using snatch blocks, choosing wire rope blocks, working load limits, etc., contact me or any one of our sales specialists at 800-660-3585. We’ll be happy to help.
