Note: 1. The straight side diameter of the chain link refers to the average value of the measured values of the same cross-section in two directions perpendicular to each other. 2. The minimum inner width a and the maximum outer width b of the link are measured on the width of the straight side outside the welding part. 3. The arc radius r is measured in the arc area between 1.2d and 120°.
