After manganese phosphating treatment, the surface wear resistance and corrosion resistance of rope steel wire are improved in an all-round way, and the fatigue life of phosphating coated steel wire rope is greatly improved because it is not easy to wear and corrosion. The fatigue life is 3-4 times that of smooth steel wire rope with the same structure (under comparable conditions in laboratory), which can be verified by fatigue test. If you have your own fatigue testing machine, you can do a comparative test yourself. This test result is the most credible. The service life of wire rope is proportional to the fatigue life, and the fatigue life is also extended in the same proportion.
According to the approximate market price of manganese phosphating coated wire rope, the price of manganese phosphating coated wire rope is higher than that of smooth wire rope, and the service life extension is much higher than the price increase. Therefore, the daily average use cost of phosphating coated steel wire rope is only about 30% of that of smooth steel wire rope, which is lower in use cost and higher in cost performance. .
Compared with smooth steel wire rope, manganese phosphating coated steel wire rope has longer service life, lower unit use cost and better stability. Phosphating coated steel wire rope is produced by patented technology, because it is difficult to buy because it is in short supply at present, so we should ask more wire rope manufacturers. Please note that the purchase invoice must indicate the names of wire ropes such as phosphating coated wire ropes to prevent illegal enterprises from infringing their legitimate rights and interests. In addition, patented products will generally mark the patent number on the outer packaging of steel wire rope, and the warranty should have main technical indicators, such as the type and weight of phosphating film (phosphating film has an important impact on the service life of steel wire rope, such as wear resistance and corrosion resistance).
