Te Tapahi me te Hanga

Ka taea te tapahi, te takai, te tā, te piko, te whakarewa, te mīhini rānei i te waea kōtaha kia oti ngā wāhanga. Ka whakapakeketia ngā momo Austenitic pēnei i te 304 me te 316 i te wā e tapahi ana, e hanga ana hoki. Ka whakaitihia ngā kopa me te ngatata e ngā taputapu koi, ngā whāngai whakahaeretia me ngā radius piko tika. He māmā ake te hanga i te rauemi kua whakawerahia, engari ka nui ake te pakari o te āhua o te waea kumea mārō.

Te Whakarewa me te Maimoatanga Wera

Ko te 304L me te 316L te mea e pai ake ana ki ngā wāhi e hiahia ana kia iti ake te ihirangi waro mō ngā huihuinga waea kōtaha kua whakarewaina. Kāore e whakapakeketia ngā momo Austenitic mā te maimoatanga tinei-me-te-whakamahana tikanga; ka whakanuia te kaha mā te mahi matao. Ka taea te whakapakeke i te momo 420 mā te huringa maimoatanga wera whai tohu, engari kāore te 430 e whakapakeketia pērā i te maitai kore waikura martensitic.
