Phosphating coated steel wire rope is a Chinese invention patent. Imported steel wire ropes are all smooth steel wire ropes without any wear-resistant protective coating. Manganese phosphate coated steel wire ropes are generally selected in accordance with national standards, GB8918-2006 important purpose steel wire ropes. The manganese phosphate coating is a wear-resistant coating formed by a chemical reaction between the surface of the steel wire and the phosphating solution. It is firmly combined with the steel wire matrix and is extremely wear-resistant. It also has good anti-corrosion capabilities and its fatigue life far exceeds that of smooth steel wire ropes. It is an upgraded product of smooth steel wire rope and can completely replace imported steel wire rope. Because the manganese-based phosphate-coated steel wire rope has an ultra-long service life, its average daily cost is only about one-third of that of smooth steel wire rope. Port gantry cranes or elevators and mine hoists can all use domestic manganese-based phosphate-coated steel wire ropes in accordance with national standards.
