China is a large manufacturing country and is transforming into a manufacturing powerhouse. To ensure that machines and equipment are lightweight, high performance, fatigue-resistant, and have a long life, it is important to monitor their residual stress levels during design, manufacturing, and use.
There are 2 proven and reliable methods for residual stress measurement, X-ray method and blind hole method. Italy SINT MTS3000 fully automatic blind hole method stress meter is the only instrument that meets the requirements of ASTM E837-13 non-uniform and uniform distribution and GB/T31310-2014 method A. The maximum speed is 400,000 revolutions per minute, and it can measure composite materials such as metals and polymers, and it has been widely used by major research institutes, universities and enterprises in China.
