MRC series mechanical creep and rupture testing machine with single-lever structure is designed for long-term creep and stress rupture test applications. The series mechanical creep and rupture testing system is mainly for the metallic materials under room or elevated temperature according to GB/T2039, GB/T 20120, EN ISO 204-2009 and ASTM E139. The creep and rupture testing machine can also maintain constant loads for extended periods of time. Through the mechanical advantage of the lever arm loading system, constant loads can be maintained with a high degree of accuracy for long duration. This creep and rupture tester uses dead weights without continuous operation and the dependency of a mechanically powered drive. The creep and rupture testing system is an ideal equipment for metallurgy manufacturer, research institute, colleges and other relevant factories and mines.
