Manganese-based phosphate-coated steel wire rope, a Chinese invention patent, has been strongly sought after by the majority of users of steel wire ropes since it entered the market in 2011, and has been in short supply. Of course, the cost-effectiveness of manganese-based phosphate-coated steel wire ropes It is also the highest and has the longest fatigue life. The longest fatigue life is enough to prove that it is the most advanced technology in the world's steel wire rope manufacturing field.
Manganese phosphate coated steel wire rope is a steel wire rope twisted with manganese phosphate coated steel wire (the wire rope is directly twisted without drawing after phosphating). The weight of the phosphate coating is generally 10-30 grams/square meter, which can greatly improve the wear resistance and corrosion resistance of the steel wire surface. The fatigue life is 3-4 times that of smooth steel wire ropes, and can reach up to 5 times under laboratory conditions. It can be verified and compared through fatigue tests. The improvement in fatigue life is related to the rope structure and the properties of the phosphate film. The wear resistance of the phosphate film is related to its composition and film weight.
Although the current price of manganese-based phosphate-coated steel wire ropes is higher than that of smooth steel wire ropes, because its service life is far longer than that of smooth steel wire ropes, the average daily usage cost of manganese-based phosphate-coated steel wire ropes is only that of smooth-coated steel wire ropes. About 30% of steel wire ropes are very cost-effective for the majority of steel wire rope users. They can save the cost of using steel wire ropes. This is also the reason why manganese phosphating coated steel wire ropes have been in a rush to buy, and can provide lifting equipment manufacturers with bring great economic benefits.
