He Tirohanga Whānui mō te Paipa Kowiri tira 201
Ko te Kowiri tira 201 he kowiri tira austenitic chromium-nickel-manganese i hangaia hei tiaki i te nikara. He iti ake te utu o te SS 201 hei whakakapi i ngā kowiri tira Cr-Ni tuku iho pērā i te 301 me te 304. Ka whakakapia te nikara mā te tāpiri i te manganese me te hauota. Kāore e taea te whakapakeke mā te maimoatanga wera, engari ka taea te mahi matao ki ngā kaha kume teitei. Ko te SS 201 he kore-aukume i roto i te āhua whakamahana, ā, ka huri hei aukume ina mahi matao. Ka taea te whakakapi i te SS 201 mō te SS301 i roto i ngā tono maha.

Te Hanga
Ka taea te hanga i te Kowiri tira Momo 201 mā te hanga pae, te hanga hurihuri me te piko parai i te huarahi ōrite ki te Momo 301. Heoi, nā tōna kaha ake, tera pea ka nui ake te kaha o tōna pūmau. Ka taea te tuhi i tēnei rauemi pērā i te Momo 301 i te nuinga o ngā mahi tuhi mena ka nui ake te mana e whakamahia ana, ā, ka piki ake te pēhanga pupuri.
Te Maimoatanga Wera
Kāore e taea te whakapakeke i te Momo 201 mā te whakamahana. Te whakamahana: Te whakamahana i te 1850 – 1950 °F (1010 – 1066 °C), kātahi ka tineia ki te wai, ka whakamatao tere rānei i te hau. Me pupuri te pāmahana whakamahana kia iti rawa, kia rite ki ngā āhuatanga e hiahiatia ana, nā te mea he nui ake te tauine o te Momo 201 i te Momo 301.
Āheitanga whakarewa
Ko te akomanga austenitic o ngā maitai kore waikura e kiia whānuitia ana he mea ka taea te whakarewa mā te whakamahi i ngā tikanga honohono me te ātete noa. Me whai whakaaro nui kia kore ai e "pakaru wera" te whakarewa mā te whakarite i te hanganga o te ferrite i roto i te putunga whakarewa. Pērā i ētahi atu momo maitai kore waikura austenitic chrome-nickel kāore te waro e herea ki te 0.03%, ki raro iho rānei, ka pāngia pea te rohe e pāngia ana e te wera whakarewa, ā, ka pāngia e te waikura intergranular i ētahi taiao. Ko tēnei koranu motuhake e kiia whānuitia ana he ngoikore ake te kaha ki te whakarewa i te koranu tino noa o tēnei akomanga koranu, te Momo 304L Koranu Waikura. Ina hiahiatia he whakakī whakarewa, ko te AWS E/ER 308 te mea tino tohua. E mōhiotia whānuitia ana te Momo 201 Koranu Waikura i roto i ngā tuhinga tohutoro, ā, ka taea te tiki atu i ētahi atu kōrero mā tēnei ara.
