How to inspect stainless steel wire rope?

According to the structure of the steel wire rope core, stainless steel wire ropes can generally be divided into hemp-core stainless steel wire ropes and steel-core stainless steel wire ropes. Now let’s discuss the difference between the steel cores of hemp cores and stainless steel wire ropes. The hemp-core stainless steel wire ropes are composed of hemp ropes in the middle. The steel core stainless steel wire rope is composed of the stainless steel wire rope in the middle.

Steel wire ropes with steel cores are more wear-resistant than hemp-core stainless steel wire ropes. It has a long service life, high breaking tension and low softness. Steel-core stainless steel wire ropes are generally suitable for cranes or windlass due to their wear resistance and compressibility. Steel hollow The price of stainless steel wire rope is slightly higher than that of bast stainless steel wire rope, but considering the service life and relatively good stainless steel wire rope tension, the cost of steel hollow stainless steel wire rope is relatively low.

Different steel wire ropes have different characteristics and uses, and their grindability, service life and performance-price ratio are different. Users can consider which stainless steel wire rope to choose according to their actual conditions.

We know that stainless steel wire rope has the characteristics of high temperature resistance, fatigue resistance, fracture resistance, long service life, and good durability. However, if the stainless steel wire rope is not checked, various problems will occur.

Appearance inspection: check the surface, structure, twisting method and twisting quality of the stainless steel wire rope diameter (roundness). Stainless steel wire rope breaking test: stainless steel wire rope partial or complete disassembly or single wire test, calculating the total tensile force of the stainless steel wire rope wire breaking , Check the performance of the steel wire rope on the stainless steel wire rope.

Stainless steel wire rope breaking tensile test: Test the ability of stainless steel wire rope to withstand breaking tensile force under unidirectional static tension. Relaxation test: Under the action of initial tension, the stress loss of stainless steel wire rope after a certain period of time is tested.
