422 pepa kowiri tira

He pai ake te kaha i nga pāmahana teitei ake, ko te Momo 422 (S42200) he momo rereke ki te Momo 403.  Ko te Momo 422 he kowiri tira martensitic whakakaha e whakamahia nuitia ana mo te pāmahana teitei ki te 1200°F. Ka taea e ia te whakamahana i te wera ki nga taumata kaha teitei. He maha nga wa e whakamahia ana i roto i nga umanga rererangi me nga umanga hiko e hiahia ana ki te kaha teitei/owehenga taumaha mai i te pāmahana rūma ki te 1200°F. ASTM A240 SS 422 Whakatakotoranga Pereti.
