Inaianei he maha nga hua ahumahi ka mahia mai i nga taonga taura waea kowiri tira.Hei tautuhi i te kowiri tira rūpahu me te iti iho, ka taea etahi tikanga me etahi tikanga.Engari he maha nga kaihoko kaore e mohio he aha te huarahi ki te tautuhi, kua whakarārangihia nga tikanga e whai ake nei mo koe.
tikanga whakamātautau aukume ko te rerekētanga noa taketake i waenganui i austenitic kowiri tira me te ferritic kowiri tira ara ohie, austenitic kowiri tira he he aukume maitai, engari i muri i te tukatuka matao i raro i te pēhanga nui ka whai i te autō paku;Engari ko te maitai chrome parakore me te maitai koranu iti he maitai autō kaha.
Ko tetahi ahuatanga whakamiharo o te taura waea kowiri tira ko te aukati i te waikura ki te waikawa nitric me te waikawa nitric waimeha, he maamaa te wehewehe mai i te nuinga atu o nga konganuku, koranu ranei.Engari ko te waro teitei 420 me te 440 maitai i roto i te whakamatautau tohu waikawa nitric he paku waikura, ko te whakarewa kore-ferrous i tutaki ki te waikawa nitric kukū ka waikura tonu, me te waikawa nitric dilute he kaha te waikura i runga i te waro maitai.
He huarahi ngawari te whakamatautau ira waro waro me nga momo taura waea kowiri tira katoa.Ko te kukū o te wairewa konukura pūkawa e whakamahia ana ko te 5%-10%.I mua i te whakamatautau tohu, me tino tangohia te waahi whakamatautau mai i te hinu, i etahi atu mea poke ranei, a me whakakorikori tetahi waahi iti ma te miihini miihini, he kakahu maeneene ranei, katahi ka heke te wai whakamatautau ki te wahi huri.Ko te rino waro noa, te rino ranei i roto i etahi hēkona ka hanga he paparanga o te parahi whakarewa o waho, a, ko te mata o te kowiri tira e kore e whakaputa i te rerenga parahi, te whakaatu ranei i te tae parahi.
