G80 load chain featrues:
1.Nominal size:Nominal diameter of the round section steel wire or bar from which the chain is made.
2.Material diameter:Diameter of the material in the chain link as measured.
3.Weld diameter:Diameter at the weld as measured.
4.Length dimensionally affected by welding:Length on either side of the center of the link, affected by welding.
5.Pitch:Internal length of a link as measured.
6.Manufacturing proof force(MPF) of chain:Force to which during manufacture the whole of the chain is subjected.
7.Breaking force( BF):Maximum force which the chain withstands during the course of a static tensile test to destruction.
8.Working load limit (WLL) of chain:Maximum mass which the chain hanging vertically is authorized to sustain in general lifting service.
9.Total ultimate elongation (A):Total extension at the point of fracture of the chain expressed as a percentage of the internal length of the test sample.
