Of PWHT: 690 ± 14 ℃ × 260h minimum simulated post-weld heat treatment: Min. Of PWHT: 690 ± 14 ℃ × 8-2h
SA387GR22CL2 mechanical performance
The mechanical properties of steel shall comply with the provisions of Table 2 (sample of simulated PWHT state):
Tensile strength Rm (Mpa) yield point Rp0.2 MPa A% Z% cold bending test b = 2a -30 ℃ Charpy impact energy J Note ①
515 to 690 310 ~ 620 ≥ 18 ≥ 45 bent 180 ° ≥ 54 (average) ≥ 47 no crack Note ② (single value)
Note: (1) shock test shall be recorded lateral expansion value and the percentage of fibrous fracture for reference.
② plate thickness T ≤ 25mm, d = 2.0a; 25mm <T ≤ 50mm, d = 2.5a; 50mm <T ≤ 100 mm, d = 3.0a; 100mm <T ≤ 150 mm, d = 3.5a. Ultrasonic testing: testing standards and conformity levels indicate a small contract. The high temperature tensile: high temperature tensile temperature and performance indicators indicate a small contract. According to the contract needs (small contracts specify the circumstances) to the maximum simulated welding heat treatment under the system of non-metallic inclusions detection and grain size detection (not crude 5). According to the contract needs (small contracts specify the circumstances) to the maximum simulated welding the hardness testing of the full thickness of the heat treatment system, the HB ≤ 220. The surface quality of the surface quality of steel should be consistent with the provisions of the ASME SA387/SA387M standards. Evaluation of temper embrittlement test (do not need to do indicate a small contract
