"Testing was performed in three phases@ presented herein in chronological order as Phase I@ II@ and III. Initially@ all testing was to be completed in two phases@ but testing anomalies in Phase II prompted re-testing of some alloys in Phase III. Alloy candidates were recommended by AWHEM membership for analysis and confirmed by API's approval of New Work Item No. 2003-100786 in June 2002. Several material suppliers and several AWHEM member companies donated material for testing. Metallurgists on the Task Group screened material certificates to ensure a ""normal"" chemistry without enhancements for the material candidates listed. Alloy chemistries from the material certificates for each of the supplied alloy candidates are provided in Table 6 through Table 16@ located at the end of this report for readability."
