The other is the determination of fatigue life of wire rope. For a kind of structural steel wire rope, such as 8 * 19s+NF- 13mm steel wire rope, a variety of sample steel wire ropes were produced through various processes, and then the sample steel wire ropes were tested on a fatigue testing machine until they broke. The test method is the same. The current test results show that the fatigue life of phosphating coated steel wire rope is 3-4 times that of steel wire rope manufactured by other processes.
If your company has a fatigue testing machine, you can do a comparative test of fatigue life between manganese phosphating coated steel wire rope and smooth steel wire rope to verify it. The test results are the most credible. For example, elevator companies basically have their own wire rope fatigue testing laboratories, and other large companies or universities are also capable of measuring the fatigue life of wire ropes.
The patent technology of phosphating coated wire rope is well understood, that is, manganese phosphating coating improves the wear resistance and corrosion resistance of wire rope surface, and the fundamental reason for the fatigue life of wire rope is that it is not easy to wear and rust.
