Re: about austenitic steel ndt Dear A.Delahaza We have over 30 years experience in the examination of austenitic steel welds . Special longitudinal angled probe have to be used to penetrate the austenitc colonnar structure . Actually we are in Korea to train people for the examination pressure vessels with heavy thicknesses .At the 15 World Conference on NDT we will present a paper on this subject . Send me you fax number , will send you material . I&T NARDONI INSTITUTE nardoni @numerica.it Brescia Italy fax 0039 -030-2667429 . Handy phone : 0039-348-2280470
---------- : where can I get some information about austenitic steel NDT, especially on electric generator, whose material is 50Mn18Cr4WN(18MnCr4)? : thank you for your help.
Re: about austenitic steel ndt EPRI (Electrical Power Research Institute) In Charlotte, South Carolina, USA has published an exhaustive recomendation manual for this exact application. The retaining rings are difficult to inspect. Inspection methods are similar to those employed during inspection of austentic piping but are different enough that specialized training would be recommended for a new inspector. The EPRI report lists both the inspection possibilities (UT, ET, PT, VT) as well as the advantages and disadvantages of each. It also touches on the fracture mechanics, flaw types, and methods of repair. The report number is EPRI EL/EM-5117-SR it can also be accessed by the topics of retaining rings, stress corrosion cracking, nondestructive testing and in-service inspection.
