Product Details
DESCRIPTION
This mechanical creep testing machine is a device used to investigate the creep characteristics of materials in high-temperature environments. Using a lever ratio of 20:1 to load the sample, a constant load is applied to the sample at high temperature, and the deformation of the sample is measured in real-time using the same method as the fracture time of the test sample. There are two types of testing machines for measuring such deformation.
