ʻO ka mua o nā mea āpau, no nā mea hana likeʻole a me nā mea pono e koho ai e koho i nā mea piliCAMH curve. No ka mea,ʻo ka mea hoʻolālā o ka lole lole e like me nāʻano likeʻole, e like me kaCAMH Eʻokoʻa nā papa hana hana.
Ma muli o ka pono a iʻole ka mea nui aCAMH ʻO ka hōʻailona lōʻihi lōʻihi o ka wikiwiki o ka wikiwiki o ka wikiwiki, nā wahi hana pilikino i ka manawa like, pono hoʻi i ka hopena kiʻekiʻe, no lailaCAMH ke kohoʻana o ka cr12mov cr12mov, maikaʻi loa ka waiwaiCAMHnā koi.CAMH ʻO ka Hardching paʻakikīʻo ka HRC63.5±1. CAMH He kiʻekiʻe loa a paʻakikī paha ka paʻakikī a paʻakikī paha nā hopena maikaʻi loa.
