Yes, surface treatment technology can greatly improve the fatigue life of steel wire ropes. The patented technology of phosphating coated steel wire ropes has proven the correctness of this point.
Every user expects the longer the service life of the steel wire rope, the better. The failure of the steel wire rope is the result of the combined effects of wear, corrosion and fatigue. Accelerated wear and corrosion will reduce the fatigue life of the steel wire rope. Therefore, it can inhibit wear and tear. And the generation and expansion of rust and delayed fatigue micro-cracks can greatly extend the service life.
The patented technology of phosphating coated steel wire ropes that has appeared in recent years uses manganese or zinc-manganese phosphating coatings to improve the wear resistance and corrosion resistance of the steel wire surface, thus greatly improving the wear resistance and corrosion resistance of the steel wire. Improve service life. The fatigue life test results of steel wire ropes have proven that this technology can greatly extend the fatigue life of steel wire ropes. The fatigue life of phosphating coated steel wire ropes is 3-4 times that of smooth steel wire ropes with the same structure. The service life of steel wire ropes has been revolutionaryly improved.
Commonly used types of steel wire ropes for lifting equipment include phosphate-coated steel wire ropes, galvanized steel wire ropes, stainless steel wire ropes or plastic-coated test wire ropes. They are used in atmospheric environments. Manganese-based phosphate-coated steel wire ropes produced with patented technology are used. The longest life span, the fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope. In heavy corrosive environments, hot-dip galvanized-phosphating double-coated steel wire rope with outstanding anti-corrosion ability is preferred, which is an upgraded product of smooth steel wire rope.
