Profile: American Stress Technologies, Inc. offers products and services for process control & quality inspection of camshafts,crankshafts, bearings, gears & valves. Our solutions offer highly effective methods for measuring stress, determining microstructure, and detecting material defects using Barkhausen noise technology, X-ray diffraction or hole-drilling technology. Our main products are Barkhausen noise analyzers, sensors & custom inspection stands, X-ray diffraction analyzers & inspection stands, and residual stress testing instrument based on hole-drilling. Several different applications use Barkhausen noise to study magnetic properties, and thus the presence or absence of material defects and residual stress levels in various components like gears, bearings, camshafts, crankshafts, universal joints & piston pins. X-ray analyzers use X-ray diffraction to measure residual stress and retained austenite contents. The prism system is based on hole-drilling technique for measuring residual stress. We provide custom inspection stands for shop floor quality control.
