Hoʻohana nui ʻia ke kila No. 45 i nā mīkini, i ka wā ʻaʻole mālama ʻia ka wela: HB≤229; lapaʻau wela: normalizing; ikehu hopena: Aku≥39J; ka ikaika kiʻekiʻe, ka plasticity maikaʻi a me ka paʻakikī, 45 # ka pā kila ma hope o ka hoʻopiʻi ʻana me ka ʻole o ka hoʻoulu ʻana, ʻoi aku ka paʻakikī ma mua o ka HRC55 (A hiki i ka HRC62). Ma hope o ka hoʻomaʻamaʻa ʻana i ka wela a me ka hoʻomaʻamaʻa ʻana, hiki iā ia ke hōʻea i ka HRC42-46, ʻaʻole hiki ke hōʻoiaʻiʻo wale i kāna mau waiwai mechanical maikaʻi, akā loaʻa pū kekahi i nā koi paʻakikī o ka ʻili. Hoʻohana ʻia ia e hana i nā hoʻoponopono ʻāpana liʻiliʻi e hiki ke kū i nā ukana nui aʻe. ʻO nā ʻāpana maikaʻi a me nā ʻāpana maʻamau nui me ka liʻiliʻi o ke koʻikoʻi, a me nā ʻāpana paʻakikī o ka ʻili e pono ʻole ai ka ikaika kumu kiʻekiʻe, e like me nā ʻōlelo aʻoaʻo, nā pou alakaʻi, nā lima kiaʻi a me nā mea ʻē aʻe.
