Committee 423 was requested to evaluate the acceptability for general prestressing applications of a low carbon, silicon-chrome, heat treated prestressing steel produced in Japan. Since heat treated prestressing steel generally has not been accepted and as North America has little experience with its use, the Committee required that an independent reviewer establish a test program and report on the findings. Professor Manuel Eiices of Spain was agreed upon as the reviewer. An extensive test program requested by Elites was agreed to by the sponsor and accepted by Committee 423. The Committee report is presented herein, based on the results of the test program and Elites’ final report. The conclusions are that silicon-chrome steel, as described in the Appendix, is comparable in corrosion behavior to stress-relieved steel now commonly used in North America and is suitable for general prestressed concrete use.
