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 nui ake te kaha owhakarewa maitaime te kore e whai paanga nui ki te pakaritanga o te maatanga 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. Chromium-molybdenum whakarewa maitai e whakamahia ana mowhakarewanga waahanga nuime nga whakarewa rino e hiahia ana kia whakapakeke hohonu.
