Computer Control Steel Strand Relaxation Testing Machine



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.
