Abstract: Metallurgical flow sheet for production of WB36 steel tube (%: 0.16C. 0.46 ~0.47Si, 1.02 ~ 1.05 Mn , 0.008 〜0.010P, 0. 001S, 0.29 ~0.30Mo, 1.17〜1.20N、0.58Cu, 0.02M), 0.05Al) is 45 t EAF-LF-VD-Φ600 mm casting bloom-piercing, Φ600 m×70 mm-Φ720 Pilger mill rolling. With controlling heating atmosphere in circular rotating furnace, temperature at soaking zone 〜1 250  , piercing temperature 1 100 °C , then blank lube tolling with three-dimensional stress by Pilger Mill, the structure of quenched-tempered WB36 steel tube is ferrite + bainite, its mechanical properties at ambient and elevated temperature, and weldability all meet the requirement of EN10216-2 standard.
