Te Whakarewatanga Mata MārōIrahiko
Paerewa: DIN 8555 (E9-UM-250-KR)
Momo Nama: TY-C65
Whakatakotoranga me te Whakamahinga:
· He hiko motuhake me te whakarewanga me ngā āhuatanga miihini tino pai.
· Austenite - Ka whakarewahia te konganuku e ngā ferrite. He kaha teitei, he ātete hoki ki te pakaru.
· He tino pai mō te hono i ngā maitai uaua ki te whakarewa, ina nui rawa ngā tono mō te hononga whakarewa.
· He ātete pakari ki te pakaru ina honoa ngā konganuku matua he uaua te whakarewa, pērā i ngā maitai austenitic me te ferritic, ngā maitai konupora-nui me ngā maitai koranu me ngā maitai kore-koranu, ngā maitai ka taea te whakamahana me ngā maitai taputapu. Ngā tono i roto i te whakatika me te tiaki i ngā wāhanga mīhini me te taraiwa me te whakatika taputapu.
· He tino pai hoki te whakamahi i tētahi paparanga urunga mō ēnei rauemi.
