Tensile properties. The tensile tests were performed in both ferritic (F) as well as tempered martensitic (TM) state. Fig. 5 shows the comparison of yield strength (Rp0.2) and ultimate tensile strength (Rm) of 9YWT-MATISSE in both ferritic and tempered martensitic states at various testing temperatures. In both states, the steel displayed similar trends of strength as the temperature increases. The improvement of strength at room temperature for the TM state is evident from Fig. 5. The engineering stress-strain curves (Fig. 6) show a significant strain hardening for both states at room temperature. Interestingly, the F state exhibited a yield point phenomenon at room temperature. On the contrary, the results obtained at elevated temperatures were quite different. The prominent improvement in strength for the TM state was gradually lost as both states appeared to approach a common low-strength value as the temperature increases. The strain hardening became much less significant at these temperatures. The main tensile properties for the TM state are summarized in Table 2. At room temperature, the TM state exhibited high yield strength and ultimate tensile strength of 929 and 1052 MPa, respectively. A decrease in strength was observed when the temperature increases. This decrease seemed to be more pronounced above 500°C with 156 MPa of ultimate tensile strength at 800°C. Similar statements can be made for the steel in the F state. The main tensile properties for the F state are summarized in Table 3.

Tensile properties. The tensile strength should be measured for pressure pipe applications in accordance with Test Method D638 and must meet the requirements of Section 4.3.
