22、-Rupture Properties at 1800 F (982 C) A tensile specimen, maintained at 1800 F 3 (982 C 2) while a load sufficient to produce an initial axial stress of 18.0 ksi (124 MPa) is applied continuously, shall not rupture in less than 23 hours. The test shall be continued to rupture without change of load.
23、 Elongation after rupture, measured at room temperature, shall be not lower than 8% in 4D. Tests shall be conducted in accordance with ASTM E 139. 3.5.1.3.1 The test of 3.5.1.3 may be conducted using a load higher than required to produce an initial axial stress of 18.0 ksi (124 MPa) but load shall
