300kn customization microcomputer-controlled high temperature
electronic creep endurance testing machine
Scope of Application:
LR-RD300 microcomputer-controlled electronic creep endurance
testing machine is mainly used for testing the mechanical
properties of superalloys, titanium alloys, other ferrous metals
and non-ferrous metals, measuring the steady state creep rate,
creep limit, creep elongation, lasting break time, lasting strength
limit, elongation after lasting break, section shrinkage, lasting
notch sensitivity coefficient.
