[0032] The main chemical element content (percentage by weight) of the alloy is: 0.05% to 0.15% of C content, 20.0% to 24.0% of Cr content, 20.0% to 24.0% of Ni content, 13.0% to 16.0% of W content, 13.0% to 16.0% of W content, La content 0.03% ~ 0.12%, Si content 0.20% ~ 0.50%, Fe content ≤ 0.30%, B content ≤ 0.015%, Mn content ≤ 1.25%, P content ≤ 0.020%, S content ≤ 0.015 %, containing Ag ≤ 0.0010%, containing Bi ≤ 0.0001%, containing Pb ≤ 0.0010%, containing Cu ≤ 0.07%, and the balance being Co.
[0033] The steps of this method are as follows:
[0034] Step 1: Prepare intermediate ring blank
[0035] Such as figure 1 As shown, according to the structural characteristics of the cobalt-based superalloy multi-step large-scale special-shaped ring 1, the cross-section of the forging is cut layer by layer equidistantly from the height direction with the help of drawing software, and the cross-sectional area data of the multi-step large-scale special-shaped ring 1 is obtained ...
