Detection Content

Detection Purpose: Check the tensile stress relaxation of steel wire rope strand

Detection range: Steel wire ropes and twisted strands used for mine hoisting, blast furnace hoisting, large-scale cas

      The specimen is heated to a specified temperature at which the tensile strain remains constant. The residual stress of the specimen is measured. The whole process can be either continuous or discontinuous.


Bulk testing can be used to test the tensile stress relaxation properties of metal materials under constant strain and temperature.
