Embodiment A1-A5 and comparative example B1-B2
[0056] The steel pipes in Examples A1-A5 and B1-B2 were manufactured according to the following steps:
[0057] (1) Smelting: after refining outside the furnace and vacuum degassing, the mass percentage distribution ratio of each chemical element in Examples A1-A5 and B1-B2 is shown in Table 1;
[0058] (2) Continuous casting into a round billet or casting into a square billet, and rolling into a round tube billet after casting;
[0059] (3) Heating and soaking: heating to AC3 and above to keep warm and soak;
[0060] (4) Steel pipes are rolled in the austenite phase zone, and the final rolling temperature is greater than 880°C;
[0061] (5) Cool to room temperature to obtain a hot-rolled product.
[0062] It can also continue to normalize, and the normalizing temperature is 860-940°C to obtain a normalized product.
[0063] Table 1 lists the mass percentage distribution of each chemical element in the steel pipes in Examples A1-A5 and Comparative Examples B1-B2 of this cas...
