7×19 and 7×7, which are two kinds of commonly used steel wire ropes, are 6-strand steel core steel wire ropes. The former is composed of 19 steel wires and the latter is composed of 7 steel wires. When the diameter of the steel wire rope is the same, the former is softer and the latter is harder.

When used in the atmospheric environment, the service life of manganese phosphating wear-resistant coating steel wire rope far exceeds that of smooth steel wire rope. There is 15-40g / m2 manganese phosphating film on the steel wire surface, which can prevent wear and rust and prolong the service life. The effect is more than oiling and maintaining the steel wire rope every day. When purchasing manganese phosphating wear-resistant coating steel wire rope, the heavier the phosphating film on the steel wire surface, the better. In order to buy genuine products, pay attention to the patent number on the steel wire rope packaging wooden shaft, In addition, the weight range of phosphating film must be checked after arrival. The weight of phosphating film can be determined by electronic scale, beaker and caustic soda with an accuracy of 0.001 G.
