254SMo Rawa Rawa
Ko te 254SMO he kowiri tira austenitic.Na te nui o te ihirangi molybdenum, he tino kaha te aukati ki te rua me te waikura kapiti.Ko tenei karaehe o te kowiri tira i whakawhanakehia, i whakawhanakehia hei whakamahi i nga taiao hauhaura penei i te wai moana.He pai hoki a 254SMO ki te waikura rite.Ina koa i roto i nga waikawa halide-kei roto, he pai ake te maitai ki te kowiri tira noa.Kei roto i tana C<0.03%, no reira ka kiia he kowiri tira austenitic parakore (<0.01% ka kiia hoki he kowiri tira super austenitic).Super kowiri tira ko te momo o motuhake kowiri tira.Tuatahi, he rereke mai i te kowiri tira noa i roto i te hanganga matū.E tohu ana ki te kowiri tira teitei kei roto i te nickel teitei, te chromium teitei me te molybdenum teitei.I roto ia ratou, ko te mea tino rongonui ko 254SMo kei roto 6% Mo. Ko tenei ahua o te maitai he tino pai te aukati o te waikura o te rohe, me te pai o te pai o te pitting corrosion resistance (PI≥40) me He pai ake te awangawanga o te waikura me te whakakapi mo te Ni- koranu e pa ana me te koranu titanium.Tuarua, i runga i nga ahuatanga o te teitei o te pāmahana, te aukati waikura ranei, he pai ake te kaha o te pāmahana teitei, te aukati waikura ranei, kaore e taea te whakakapi mo te 304 kowiri tira.I tua atu, mai i te whakarōpūtanga o te kowiri tira, ko te hanganga metallographic o te kowiri tira motuhake ko te hanganga austenite metallographic pumau.
I te mea ko tenei kowiri tira motuhake he papanga teitei, he tino uaua te mahi hangahanga.Ko te tikanga, ka taea e te tangata te whakawhirinaki anake ki nga tikanga tuku iho hei hanga i tenei kowiri tira motuhake, penei i te whaowhia, te whaowhia, te hurihuri me etahi atu.
254SMo Nga Waahanga Tono Rawa
1. Te moana: nga hanganga o te moana i roto i te taiao o te moana, te whakaheke i te wai o te moana, te ahumoana wai moana, te whakawhiti wera o te moana, me etahi atu.
2. Marae tiaki Taiao: taputapu hau rewharewha desulfurization mo te whakangao hiko waiariki, maimoatanga wai para, etc.
3. Te mara hiko: te whakaputa hiko karihi, te whakamahi matawhānui i te waro, te hanga hiko tai moana, aha atu.
4. Te mara matū: te hinu hinu, te matū me te taputapu matū, me etahi atu.
5. Te mara kai: te hanga tote, te mahi ranu soy, etc.
6. Te taiao katote pūhaumāota teitei: te ahumahi pepa, nga momo momo whakamaarama
