Fretting fatigue is the main reason for the failure of steel wire ropes used in atmospheric environment. At present, the first preventive measure against fretting fatigue in the field of steel wire rope in the world is phosphating coated steel wire rope produced by patented technology. After manganese phosphating or zinc-manganese treatment, the wear resistance and corrosion resistance of steel wire surface are improved in an all-round way, and the fatigue life of steel wire rope is greatly improved, which is three times that of smooth steel wire rope with the same structure. The comparison of the highest test values has reached an astonishing four times (under comparable conditions in the laboratory), which can be verified by fatigue test. If you have your own fatigue testing machine, you can do your own comparative test. This test result is the most credible. The service life of wire rope is proportional to the fatigue life, and the fatigue life will also be extended in proportion.
Phosphate coated steel wire rope has longer service life, lower use cost and better stability than smooth steel wire rope. Phosphating steel wire rope is produced by patented technology. Because it is in short supply, it is difficult to buy it at present, so it is necessary to ask the wire rope manufacturer more. Please note that the name of wire rope, such as phosphating wire rope, must be indicated in the purchase invoice to prevent illegal enterprises from infringing their legitimate rights and interests. In addition, patented products are generally painted with patent numbers on the outer packaging of wire ropes. The warranty shall include the main technical indicators such as the type and weight of phosphating film (phosphating film has a great influence on the service life of wire rope, such as wear resistance and corrosion resistance, etc.) for reference only.
