Te whakamahi i tetukanga makanga haumi, Ko te hangahanga whakarewa RMC e kaha ana ki te whakatutuki i nga whakaritenga rauemi e ai ki nga paerewa ASTM, SAE, AISI, ACI, DIN, EN, ISO, me GB. Neke atu i te 100 nga koranu ferrous me te kore-ferrous rereke e maka ana e matou nga waahanga ma te whakamahi i nga paearu hoahoa uaua. Ka hangaia a maatau whakangaonga whakangao me te hangahanga kia rite ki te ahua kupenga, ka whakaiti i te hiahia mo te miihini tuarua.
Chromium-molybdenum whakarewa maitai e whakamahia nuitia ana i roto i nga mara ahumahi me nga taonga miihini teitei. Ko te taapiri o te molybdenum ki te rino chromium ka taea te whakanui ake i te kaha o te whakarewanga rino me te kore e pa ki te kaha o te whakapanga o te rino whakarewa. Ano, chromium-molybdenum maka maitai he tino pai te mahi pāmahana teitei me te ātete ngokingoki. I muri i te tinei me te whakamaarama, te whakarite ranei i te maimoatanga wera, ka taea e te chromium-molybdenum te whakarewa te maitai te whiwhi taonga miihini pai.
Ka taea e te Molybdenum te whakapai ake i te pakari o te maka rino me te whakaiti i te ngawari o te riri o te whakarewa. Ka whakamahia te chromium-molybdenum cast steel mo nga waahanga nui me nga whakarewa rino e hiahia ana kia whakapakeke hohonu.
