Abstract��Superalloy GH536 seamless rectangular tube is a kind of steel tube with a hollow section and no seams along its length direction. Because there is no testing method and standard for this tube, in order to control the quality of the tube, on the basis of possible defects in the process production, combined with non-destructive testing methods, the seamless rectangular tube is tested by immersion ultrasonic testing when in the semi-finished condition and the finished tested with eddy current testing for the effective control of the tube quality. The analysis of metallography of the tube indicates that it is feasible for the testing of superalloy GH536 rectangular tube.
