Which type of steel wire rope is the most durable?
2026-01-15
The durability of the wire rope depends on the usage scenario and material technology. Overall, galvanized steel core wire rope is the most durable type for general scenarios. For special environments, there are more suitable options available. The classification is as follows:
For general scenarios: Hot-dip galvanized steel core wire rope Core advantages: The hot-dip galvanizing process makes the zinc layer bond more tightly with the steel wire, and its corrosion resistance is 2-3 times that of electro-galvanizing; the steel core structure is more resistant to stretching and bending than the fiber core, and is less prone to deformation. Applicable scenarios: Outdoor lifting, tower cranes, elevators, fence traction and other daily scenarios, which can withstand dampness, sunlight and other ordinary harsh environments. For strong corrosive environments: Stainless steel wire rope Core advantages: Made of 304 or 316 stainless steel material, it is resistant to acids and alkalis, and salt fog, and the corrosion rate is much lower than that of galvanized wire rope. Note: The price is 2-5 times higher than that of galvanized wire rope, and its strength is slightly lower than that of the same specification carbon steel wire rope, and it is not suitable for heavy-load hoisting. For heavy-load and high-frequency scenarios: Compact strand wire rope Core advantages: Through special compaction process, the gaps between the steel wires are smaller, and the wear resistance and fatigue resistance are improved by more than 30%, and there are fewer problems of broken wires and loose strands. Applicable scenarios: Mine lifting, port loading and unloading, large cranes, etc., which require high-frequency bending and heavy loads. Key factors affecting durability: 優(yōu)先 choose steel core over fiber core， as it has stronger resistance to stretching and compression； For galvanizing layer， choose hot-dip galvanizing， which is more resistant to wear and corrosion than electro-galvanizing； For wire rope twisting method， choose cross-twisting， which is less likely to loosen than the same-direction twisting. |
