Pae Papatahi Kowiri tira 420
Whakaahuatanga Poto:
Ngā Kaiwhakarato Pae Papatahi Din 1.4034 SS 430, Pae Papatahi SS UNS S42000, Pae Papatahi Kowiri tira 420, Pae Matao Kowiri tira 420 i Haina.
He maitai waro-teitei te maitai kore waikura karaehe 420, he iti rawa te ihirangi chromium o te 12%. Pērā i ngā maitai kore waikura katoa, ka taea hoki te whakapakeke i te karaehe 420 mā te whakamahana. He pai te ngāwari o te whakarewa i roto i tōna āhua whakamahana, ā, he tino pai ngā āhuatanga ātete ki te waikura ina orohia te konganuku, ina whenuahia te mata, ina whakapakeketia rānei. Ko tēnei karaehe te mea tino pakeke – 50HRC – i roto i ngā karaehe maitai kore waikura katoa me te 12% chromium.
