l of delta ferrite in austenitic stainless steel welds is reviewed to determine its conformance with the acceptance criteria stated in Subsection II.4.D of this SRP section. The reviewer verifies that appropriate filler metal acceptance tests have been conducted and that a certified materials test report has been received. The reviewer also verifies that the applicant's program is in compliance with the staff positions in Regulatory Guide 1.31 and the more stringent criteria specified in II.4.D where applicable. The information submitted by the applicant regarding control of electroslag weld properties for austenitic stainless steel materials is reviewed for conformance with the acceptance criteria discussed in Subsection II.4.D of this SRP section. 5.2.3-19 Revision 3 - March 2007 The review of information on the control of electroslag weld properties in austenitic stainless steels is essentially the same as that discussed previously for ferritic steels. However, because electroslag-welded austenitic stainless steels have very high impact resistance, the checks are: (1) a macroetch test is used to provide assurance that the solidification pattern is in accordance with the requirement of the acceptance criteria shown in Subsection II.4.D of this SRP section, and (2) wrought stainless steel parts are solution heat treated after welding. The review procedure for information submitted on welder qualification for limited accessibility areas, applicable to austenitic stainless steels, is the same as that for ferritic steels, which has been discussed previously under Subsection III.3.B.(3) of this SRP section. E. The procedures for review of nondestructive examination of tubular products fabricated from austenitic stainless steel are the same as those discussed for similar ferritic products in Subsection III.3.C of this SRP section, and the acceptance criteria are as shown in Subsection II.4.E of this SRP section. F. Cast austenitic stainless steel is susceptible to
