17、or Heading: As ordered by the forging, flash welded ring, or heading manufacturer. 3.3 Heat Treatment: Bars, forgings, and flash welded rings shall be solution heat treated by heating to 2150 F 25 (1177 C 14), holding at heat for not less than 1 hour, and quenching in water. 3.4 Properties: The prod
18、uct shall conform to the following requirements: 3.4.1 Bars, Forgings, and Flash Welded Rings: 3.4.1.1 Hardness: Shall be as follows, determined in accordance with ASTM E 10: 3.4.1.1.1 Bars and Forgings: 156 to 217 HB, or equivalent (See 8.2). 3.4.1.1.2 Flash Welded Rings: 156 to 241 HB, or equivale
19、nt (See 8.2). 3.4.1.2 Stress-Rupture Properties at 1350 F (732 C): A tensile specimen, maintained at 1350 F 3 (732 C 2) while a load sufficient to produce an initial axial stress of 32.0 ksi (221 MPa) or higher is applied continuously, shall not rupture in less than 23 hours. The test shall be conti
20、nued to rupture without change of load. Elongation after rupture, measured at room temperature, shall be not less than 10% in 4D. Test shall be conducted in accordance with ASTM E 139. 3.4.1.2.1 The test of 3.4.1.2 may be conducted using incremental loading. In such case, the load required to produc
21、e an initial axial stress of 32.0 ksi (221 MPa) or higher shall be used to rupture or for 23 hours, whichever occurs first. After the 23 hours and at intervals of 8 to 16 hours thereafter, the stress shall be increased in increments of 2.0 ksi (14 MPa). Time to rupture and elongation requirements sh
