c. Daidaita da weel karfe a ciki. Appropriately increase the content of Mn, C, and N in the single-phase austenitic steel, and add a small amount of trace elements such as cerium, pickaxe, and tantalum (which can refine the weld structure and purify the grain boundary), which can reduce the sensitivity of thermal cracking.
