SUS410 / SUS420J2 / SUS430 kowiri tira peera Whakataurite：
SUS410: Ko te Martensite te tohu i te tohu maitai, me te kaha nui, me te pakeke pakeke (aukume); te aukati i te waikura koretake, kaore e pai mo te whakamahi i nga taiao tino waikura; iti te ihirangi C, te pai o te mahi, ka taea te whakapakeke i te mata e te maimoatanga wera.
SUS420J2: Ko te Martensite te tohu i te tohu maitai, me te kaha nui, me te pakeke pakeke (aukume); te ngoikore o te aukati, te koretake o te tukatuka me te ngawari, me te aukati i te kakahu pai; ka taea te whakamaera i te wera kia pai ake ai nga miihini. Kei te whakamahia whanui mo te tukatuka maripi, paparua, vaolo, rangatira, me te teepu.
SUS430: Te reiti o te rewharewha waiariki, te koretake me te aukati hāora. He pai mo nga taputapu wera-aukati, kaitahu, taputapu o te kaainga, akomanga 2 tepu, tepu kihini. Te utu iti, te pai o te mahi ka taea te whakakapi i te SUS304; ātete waikura pai, angamaheni maimoatanga kore-wera whakapakeke kowiri tira.

Te kaupapa o te poari kowiri tira:
Ko nga peara maitai he kowiri ehara i te waikura, engari kaore i te ngawari ki te waikura. Ko te kaupapa ko te taha o te chromium, ka hangaia he papanga waikura chromium kaha ki runga i te mata o te maitai, ka aukati i te honotanga ano i waenga i te maitai me te hau, kia kore ai e uru te oxygen i te rangi ki te maitai. poi, ma reira e aukati Ko te painga o nga peara maitai e rusting ana.
China National Standards (CNS), Japanese Industrial Standards (JIS) me American Iron and Steel Institute (AISI) te whakamahi i nga mati e toru hei tohu i nga kowiri tira rereke, e kiia whanui ana i te umanga, ko te 200 o te raupapa ko te chromium-nickel-manganese -based austenitic He kowiri tira, 300 raupapa ko te chromium-nickel austenitic he kowiri tira, 400 raupapa chromium he kowiri tira (e mohiotia ana ko te rino kowiri), tae atu ki te martensite me te ferrit.
