1. The fatigue test data prove that the fatigue life of manganese phosphide coated steel wire rope is 3-5 times that of smooth steel wire rope, which is the longest in the same structure.
2. Although the price of manganese phosphating coated steel wire rope is slightly higher than that of smooth steel wire rope, the service life of manganese phosphating coated steel wire rope is more than three times that of smooth steel wire rope, and the unit use cost is only about one third of that of smooth steel wire rope.
The above two points are the requirements of wire rope users, which can meet the requirements of users to the greatest extent. It is inevitable to eliminate smooth wire rope. Manganese phosphating coated wire rope is the most advanced technology in the wire rope manufacturing industry in the world, and foreign wire rope factories have also invented patents in China Shanzhai. Personal opinion, for reference only.
