It is mainly used in the tensile stress relaxation performance testing for pre-stressed steel wire, steel strand and pre-stressed steel bar.
Main Function and Usage
◆It is mainly used in the tensile stress relaxation performance testing for pre-stressed steel wire, steel strand and pre-stressed steel bar.
◆It can show the relationship diagram of residual testing power /relaxation rate with time, and relationship diagram of temperature and time.
◆The stress relaxation properties of the specimen in 1000 hours can be calculated by this machine.
◆It can gain the stress relaxation properties of specimen automatically and print a complete testing report.
