Ko te maitai kore waikura 303 (SS 303) tētahi o ngā wāhanga o te rōpū koranu maitai kore waikura. He maitai kore waikura austenitic te SS 303, kāore e aukume, kāore hoki e whakapakeketia. E ngana ana tēnei mahi ki te arotau i ngā tawhā tukanga huri CNC mō te rauemi SS303 pērā i te tere o te porowhita, te tere whāngai me te hohonu o te tapahi. Ka whakamahia ngā whakaurunga paninga kohu ā-tinana (PVD). Ka whiriwhiria te tere tango rauemi (MRR) me te taratara mata (SR) hei urupare putanga mō te tukanga arotau. Ka hangaia he tauira hina-pōuri i waenga i ngā uara putanga kua whakaritea me ngā uara tohu whanaungatanga hina e rite ana. Kua whakatauhia te huinga pai o te tautuhinga tawhā whakauru mō te whiwhi i ngā urupare putanga pai ake i runga i te uara tohu whakaaro hina-pōuri kua hangaia. Kua whakamahia te tikanga tātari rerekētanga hei tautuhi i te awe o ia āhuatanga whakauru ki te whakatutuki i ngā hua pai.
