2. Ho tsitsisa
Austenitic stainless steel e na le khanyetso e ntle ea kutu ka mor'a kalafo ea tharollo. Leha ho le joalo, ha ho lahla ho futhumatsoa ho 500 ° C-850 ° C kapa ho sebetsa sebakeng sena sa mocheso, chromium carbide e tla boela e theohe haufi le moeli oa lijo-thollo oa austenite, e bakang kutu ea moeli oa lijo-thollo kapa ho phunyeha ha weld. Ketsahalo ena e bitsoa sensitization. E le ho ntlafatsa ho hanyetsa ha kutu ea intergranular ea li-castings tse joalo tsa austenitic tse sa hloekang, hangata hoa hlokahala ho eketsa lisebelisoa tse kang titanium le niobium. Ka mor'a phekolo ea tharollo, futhumatsa hape ho 850 ° C - 930 ° C, 'me u pholile kapele. Ka tsela ena, li-carbides tsa titanium le niobium li qala ho theoha ho tloha ho austenite, kahoo li thibela ho na ha chromium carbide le ho ntlafatsa moeli oa lijo-thollo ho hanyetsa ha tšepe e sa hloekang.
