430 he kowiri tira, he kowiri tira 201 he pai ake?

430 te mata kowiri tira maeneene, te ngenge o te wera, te waikawa, te hau kawakore, te otinga me etahi atu parenga waikura.Te kirihou teitei, te uaua me te kaha miihini;201 Kowiri tira putorino he nga āhuatanga o te ātete waikawa, ātete alkali, kiato tiketike kahore pinholes, me ētahi atu, ko te hanga o ngā take mataaratanga, here hipoki raro me ētahi atu rauemi-kounga tiketike.201 Ka taea te whakamahi paipa kowiri tira i roto i nga paipa whakapaipai, i nga putorino ahumahi, me etahi hua papaku.

430 kowiri tira me te 201 kowiri tira rereke

430 he kowiri tira he martensitic kowiri tira, martensitic kowiri tira me te maitai koranu noa he rite nga ahuatanga o te whakapakeke ma te tinei, te martensitic chromium kowiri tira i roto i te tinei - nga tikanga whakamahana, te whakanui ake i te ihirangi o te chromium ka taea te whakanui ake i te ihirangi ferritic, na reira ka whakaiti i te pakeke me te kaha tensile.I raro i nga tikanga whakapouri, ka piki ake te pakeke o te waro iti martensitic chromium kowiri tira i te pikinga o te ihirangi chromium, i te mea ka heke paku te elongation.I raro i te ahua o tetahi ihirangi chromium, ko te piki o te ihirangi waro ka piki ake te pakeke o te maitai i muri i te tinei, ka heke te kirihou.

I muri i te tinei pāmahana iti, ka tino kitea te taapiri o te molybdenum.Ko te kaupapa matua o te taapiri molybdenum ko te whakapai ake i te kaha, te pakeke me te whakapakeke tuarua o te maitai.I roto i te martensitic chromium-nickel kowiri tira, ka taea te whakaiti i te ihirangi o te δ ferrite i roto i te maitai e te nui o te nickel, kia whiwhi te maitai i te uara pakeke teitei.

210 kowiri tira he chromium-nickel austenitic kowiri tira, austenitic kowiri tira he kore-autō, he tiketike uaua me te kirihou, engari he iti te kaha, e kore e taea ki te whakapakari i roto i te huringa wāhanga, anake ma te mahi makariri ki te whakapakari.Mena ka taapirihia te S, Ca, Se, Te me etahi atu waahanga, he pai te mahi miihini.Mena kei roto i a Mo, Cu me etahi atu mea, ka taea ano e ia te whakakore i te pirau o te waikawa pungatara, te waikawa phosphoric, te waikawa formic, te waikawa acetic, te Urea me etahi atu.Mena he iti iho i te 0.03% te ihirangi waro o taua rino, kei roto ranei a Ti, Ni, ka taea te whakapai ake i tana aukati waikura intergranular.High silicon austenitic kowiri tira waikawa nitric kukū he pai te waikura ātete.Nā te mea he matawhānui, he pai hoki ngā āhuatanga matawhānui austenitic kowiri tira, kua whakamahia whānuitia i roto i ngā āhuatanga katoa o te ao.
