Double Station Computer Control Electronic High Temperature Creep Testing Machine

1. Application:

Microcomputer-controlled electronic creep stress rupture testing machine is mainly used for testing the mechanical properties of superalloys, titanium alloys, other ferrous metals and non-ferrous metals, and measuring the steady-state creep rate, creep limit, creep elongation, Permanent fracture time, permanent strength limit, permanent elongation after fracture, section shrinkage, permanent notch sensitivity coefficient. In addition to conventional creep and durability tests, stress relaxation tests, high-temperature short-time tensile tests, cyclic loading tests (load spectrum tests), and low-cycle cycles can also be performed.
