The invention relates to and discloses a 3600-rpm high-load low-pressure stage moving blade for an industrial steam turbine. The 3600-rpm high-load low-pressure stage moving blade comprises a blade body, a blade root, and a step-shaped oblique channel girdle for integral self-locking of the blade. The height of the blade body is 467.61 mm, the axial width of the root is 103.26 mm, the diameter ofthe root is 1120 mm, and the axial width of the top is 57.73 mm. The blade root is in a fir tree shape, the total height of the blade root is 54.98 mm, and the axial width is 133.0 mm. The blade girdle is in a three-step-like shape in the circumference direction, the thickness is 4-18 mm, the axial width of the girdle is 61.46 mm, the axial width of the lower step is 21.17 mm, the axial width of the middle step is 26 mm, and the axial width of the upper step is 14.29 mm. The changing rule of the ratio T/b of the pitch from blade root section to top section to the chord length is that T/b is greater than or equal to 0.51 but smaller than or equal to 0.86; the changing rule of the ratio T/B of the pitch from blade root section to top section to the profile section axial width is that T/B isgreater than or equal to 0.53 but smaller than or equal to 1.75. The high-load final stage moving blade has the advantages of high aerodynamic efficiency, good strength performance, reasonable construction, convenient installation and the like, and the blade is applied to the 3600-rpm high-load industrial steam turbine.
