What is the quality of wire rope produced by Ningxia Xinri Hengli? Is there a manganese phosphating wear-resistant protective coating?

Hengli is a famous brand in China. In the early years, it was aided by Tianjin Yishen and Anshan steel rope, and the quality of steel rope was quite good. Phosphating coated steel wire rope is an invention patent of China, which can be found on the website of China National Intellectual Property Administration. In order to produce manganese phosphating coated steel wire rope, enterprises need to sign a contract to purchase patent license before they can legally produce it. As for whether Hengli produces manganese phosphating coated steel wire rope now, it is suggested to call the sales manager of the manufacturer so as to get accurate information. At present, manganese phosphating coated steel wire rope will replace smooth steel wire rope. Manganese phosphating coated steel wire rope has longer fatigue life and lower unit use cost, which can better meet the requirements of users. Manganese phosphating film on the surface of steel wire is a kind of wear-resistant and corrosion-resistant protective coating, which is the reason why the service life of manganese phosphating coated steel wire rope is greatly improved.
