201 Pae Kowiri tira
Whakaahuatanga
Te aukati waikura
Ko te taumata whanui o te aukati waikura Momo 201 he rite ki te Momo 301's.I roto i te nuinga o nga ahuatanga ngawari, me pai te mahi a Momo 201 hei whakakapi mo te Momo 301. He iti ake te parenga a te Momo 201 i te Momo 301. Ko te Momo 201 he 50 °F (28 °C) iti ake te atete ki te whakatauine kino i te Momo 301 ki te 1500 °F (816 °C).
Hangahanga
He rite ki te Momo 301, Momo 201 kowiri tira ka taea te hanga na roto i te hanga pae, te hanga pukapuka, me te piko o te pakaru.Engari na te kaha ake o tona kaha, ka nui ake pea te hokinga mai.I te nuinga o nga wa, ka taea te tuhi i tenei rauemi ki te Momo 301
mehemea ka nui ake te mana, ka piki te pehanga pupuri, ka mahi tuhi.
Te paihere
Ko te whakakotahitanga paerewa me nga tikanga whakawhanaunga parenga e whakaarohia ana ka taea te hono atu ki nga tira kowiri i roto i te akomanga austenitic.Ma te whakarite kia puta nga ferrite ki roto i te putunga weld, me tino tupato ki te aukati i te "pakatanga wera".Ko te rohe e pa ana ki te wera wera ka noho tairongo me te whakaraerae ki te waikura intergranular i etahi ahuatanga, pera me etahi atu karaehe kowiri tira chrome-nickel austenitic kaore te waro e whakahaeretia ki te 0.03% iti iho ranei.Ka whakatauritea ki te Momo 304L Kowiri tira, koinei te koranu tino rongonui i roto i tenei karaehe kowiri, ko te nuinga o te whakaaro he kino ake te weldability o tenei koranu.Ko te korero tino maha mo te AWS E/ER 308 ko te wa e hiahiatia ana he whakakii weld.Ka kitea etahi atu korero i roto i nga tuhinga tohutoro, e mohiotia ana mo te Momo 201 Stainless Steel.
Te maimoatanga wera
Ko te momo 201 e kore e whakapakeketia e te maimoatanga wera.Te whakaraerae: Te awhi i te 1850 – 1950 °F (1010 – 1066 °C), ka tineia te wai, ka tere ranei te whakamatao o te hau.Me noho iti te pāmahana whakahiato, kia rite ki nga ahuatanga e hiahiatia ana, na te mea ko te Momo 201 ka nui ake i te Momo 301
