Grade 43 vs Grade 70 Chain

It’s important to know the working load limits (WLL) of the chain you are using, which will be approximately one third of their break strengths – or the amount of force needed before the chain will break. The working load limit is determined by both grade and diameter and you can determine its WLL using this chart.
