Title PISC III -- Experience from UT evaluation in cast austenitic stainless steel components
- Swedish Plant Inspection Ltd., Stockholm (Sweden). Nuclear Dept.
This paper deals with the ultrasonic examination and the experience from the Swedish participation in PISC III action No. 4, capability study. It describes the possibilities and the limits of detection with standard- and more advanced techniques in cast stainless steel material. All techniques used are current practiced. The results show that the grain structure and grain sizes has a very important effect on the possibility to make an ultrasonic inspection of these kinds of materials. The results show also that inspections have to be done in two directions and to use an automated scanning devices for evaluation at noise level. The best result was obtained with a standard TRL45{degree}-0,5 MHz transducer for detection of the surface breaking flaws. This study is pertinent for PWR plants.
