As part of a long range materials development program, new commercial plant materials were evaluated for future BWR applications. These materials include ferritic, martensitic, austenitic, and austeno-ferritic stainless steels. Each alloy was characterized for chemical composition, microstructure, and mechanical properties. Stress corrosion cracking screening tests were performed in 550$sup 0$F, high-purity water containing 36 ppM oxygen on uniaxial tensile specimens stressed at 75 percent of the 550$sup 0$F ultimate tensile strength. Tests were continued to 5000 hours or failure which ever occurred first. Post- test metallographic examinations were performed on the failed specimen. Results of the evaluation program are presented. 12 fig, 3 tables. (auth)
