Selection of tensile strength of stainless steel wire rope
2024-12-23
The breaking tension of stainless steel wire rope can be said to be its important performance, which represents the tensile strength of stainless steel wire rope, therefore, when purchasing stainless steel wire rope products, pay special attention to its tensile strength.
Here we understand the principle of selection of tensile strength of stainless steel wire rope: High tensile strength can improve the dynamic load capacity and extrusion resistance of stainless steel wire rope. However, with the increase of tensile strength, the toughness of stainless steel wire rope decreases and the stiffness increases. Easy to break under heavy load and repeated bending. That is to say, the tensile strength of stainless steel wire rope is not the higher the better, the need for comprehensive consideration. The tensile strength of 1400-1850mpa stainless steel wire rope has good tensile strength, extrusion resistance, wear resistance and flexibility and other comprehensive properties, is the focus of the crane working mechanism, few tensile strength of 2000MP wire rope. Stainless steel wire rope in the actual work, in addition to the static load, acceleration, braking but also bear dynamic load, but in order to simplify the calculation, usually the dynamic load as a kind of inertial force, so as to use the static load calculation, and the safety factor will increase to meet the safety needs of the actual project. When the static method is used, the tensile strength of the stainless steel wire rope should meet the requirements of the safety factor and the diameter of the drum or pulley. Reasonable selection of the tensile strength of stainless steel wire rope is the key to improve the safety factor of the use of steel wire rope, but in actual use, maintenance should be carefully done, and the key inspection of the wearing parts should be carried out to maintain the good performance of stainless steel wire rope. |
